The question probes the understanding of the fundamental principles governing the operation of a basic DC motor, specifically how varying the applied voltage impacts its performance characteristics. A DC motor’s speed is directly proportional to the applied voltage, assuming constant magnetic field strength and load. The torque produced by a DC motor is proportional to the product of armature current and magnetic field strength. Armature current, in turn, is influenced by the back electromotive force (back EMF), which is generated as the armature rotates within the magnetic field. Back EMF is directly proportional to the motor’s speed. When the applied voltage is increased, the net voltage across the armature (applied voltage minus back EMF) increases, leading to a higher armature current. This increased current, under a constant magnetic field, results in greater torque. As the motor accelerates due to this increased torque, the back EMF also increases. The motor will continue to accelerate until the back EMF rises to a point where the armature current is just sufficient to produce the torque required to overcome the load and internal friction. Therefore, an increase in applied voltage leads to a higher operating speed and, consequently, a higher back EMF. The torque at any given speed is proportional to the armature current, and since the armature current is determined by the difference between applied voltage and back EMF, increasing the applied voltage allows for a higher steady-state speed where the back EMF balances the increased applied voltage. This means the motor can reach a higher speed before the back EMF becomes significant enough to limit the current to the level required by the load.

Therefore, a hypothesis that is repeatedly shown to be incorrect through rigorous testing is not merely a “bad guess” but a crucial data point that guides future research towards more accurate explanations or designs, aligning with the Polytechnic University of Chihuahua’s emphasis on evidence-based problem-solving and innovation.

The question probes the understanding of ethical considerations in engineering design, specifically within the context of sustainable development, a core principle at the Polytechnic University of Chihuahua. The scenario involves a conflict between immediate economic benefit and long-term environmental impact. A responsible engineer, adhering to professional ethics and the university’s commitment to societal well-being, would prioritize a solution that minimizes negative externalities, even if it incurs higher initial costs. This aligns with the concept of the precautionary principle and the triple bottom line (people, planet, profit). The most ethical approach involves a thorough lifecycle assessment and the integration of robust environmental safeguards. Considering the Polytechnic University of Chihuahua’s emphasis on innovation for social good and its research strengths in environmental engineering and sustainable technologies, the correct answer reflects a proactive, ethically grounded decision-making process that anticipates and mitigates potential harm. The other options represent less responsible or incomplete approaches, either by deferring responsibility, underestimating risks, or prioritizing short-term gains over long-term sustainability, which would be contrary to the institution’s values.

The question probes the understanding of the fundamental principles of sustainable urban development, a core tenet in many engineering and urban planning programs at institutions like the Polytechnic University of Chihuahua. The scenario involves a city aiming to reduce its environmental footprint while fostering economic growth. The correct approach must integrate multiple facets of sustainability. A holistic approach to urban sustainability, as advocated by leading urban planning theories and research, emphasizes the interconnectedness of environmental, social, and economic factors. Environmental considerations include resource efficiency, waste reduction, and the promotion of green spaces. Social aspects involve community engagement, equitable access to services, and the preservation of cultural heritage. Economic viability necessitates job creation, support for local businesses, and investment in resilient infrastructure. The scenario presented requires a strategy that balances these three pillars. Option A, focusing on technological solutions like smart grids and advanced waste management, addresses the environmental aspect effectively. However, it might neglect the social equity and economic inclusivity crucial for long-term success. Option B, prioritizing community-led initiatives and affordable housing, strongly emphasizes the social dimension but could potentially overlook the economic feasibility and technological advancements needed for large-scale impact. Option C, concentrating on economic incentives for green industries and infrastructure upgrades, targets economic growth and environmental improvements but might not adequately address social cohesion or the needs of vulnerable populations. Option D, which advocates for a multi-pronged strategy that simultaneously enhances public transportation networks, invests in renewable energy sources, implements comprehensive recycling programs, and fosters local green job creation through public-private partnerships, represents the most integrated and therefore effective approach. This strategy directly addresses environmental concerns (public transport, renewables, recycling), economic development (green jobs, partnerships), and implicitly supports social well-being through improved accessibility and employment opportunities. This aligns with the Polytechnic University of Chihuahua’s commitment to producing graduates who can tackle complex, multifaceted challenges with innovative and responsible solutions. The synergy between these elements is key to achieving genuine, lasting urban sustainability.

The question probes the understanding of a fundamental principle in materials science and engineering, particularly relevant to the Polytechnic University of Chihuahua’s focus on applied sciences and manufacturing. The core concept being tested is the relationship between material properties, processing, and performance under specific environmental conditions. The scenario describes a component designed for a corrosive environment, implying that the material selection and its surface treatment are critical for longevity and functionality. The question asks to identify the most appropriate strategy for enhancing the component’s resistance to degradation. Let’s analyze the options in the context of materials science principles: * **Surface Alloying/Coating:** This involves modifying the outermost layer of the material to impart desired properties, such as corrosion resistance, hardness, or wear resistance. Techniques like electroplating, chemical vapor deposition (CVD), or physical vapor deposition (PVD) can introduce elements or compounds that are inherently more resistant to the specific corrosive agents present. For instance, applying a chromium or nickel alloy coating to a steel component can significantly improve its resistance to acidic or saline environments. This approach directly addresses the surface interaction with the corrosive medium. * **Bulk Alloying:** This involves altering the composition of the entire material by adding alloying elements to the base metal. While effective for improving general properties, it might not be the most efficient or cost-effective solution if only surface protection is required, especially for large components. Furthermore, the bulk properties might need to remain unchanged for mechanical reasons. * **Heat Treatment:** Heat treatments like annealing, quenching, or tempering primarily affect the microstructure of the material, influencing its mechanical properties (strength, hardness, ductility) and sometimes its corrosion resistance by altering phase distribution or reducing internal stresses. However, they typically do not introduce new elements or create a protective barrier against aggressive external agents as effectively as surface modification. * **Mechanical Stress Relieving:** This process aims to reduce residual stresses within a material, which can sometimes mitigate stress corrosion cracking. However, it does not fundamentally alter the material’s chemical reactivity or provide a barrier against direct chemical attack. Considering the scenario of a component in a corrosive environment, the most direct and often most effective method to enhance resistance is by modifying the surface where the corrosive attack occurs. Surface alloying or coating provides a dedicated protective layer that can be specifically engineered for the anticipated corrosive agents, offering a targeted solution. This aligns with the practical engineering considerations often emphasized at institutions like the Polytechnic University of Chihuahua, where the application of scientific principles to solve real-world problems is paramount. The ability to select and apply appropriate surface engineering techniques is a key skill for graduates entering fields like manufacturing, aerospace, and chemical processing.

The question probes the understanding of the fundamental principles of sustainable urban development, a core tenet in many engineering and architectural programs at institutions like the Polytechnic University of Chihuahua. The scenario involves a city planning committee tasked with revitalizing an industrial district. The key is to identify the approach that best balances economic growth, social equity, and environmental protection, which are the three pillars of sustainability. Option (a) proposes a strategy that integrates mixed-use development, green infrastructure, and community engagement. Mixed-use development reduces the need for extensive commuting, thereby lowering carbon emissions and improving air quality. Green infrastructure, such as permeable pavements and urban green spaces, helps manage stormwater runoff, mitigate the urban heat island effect, and enhance biodiversity. Community engagement ensures that the revitalization plan addresses the needs and aspirations of the local residents, fostering social equity and buy-in. This holistic approach directly aligns with the principles of sustainable urban planning, aiming for long-term viability and well-being. Option (b) focuses solely on attracting new industries, which might boost the economy but could neglect environmental concerns and social impacts, potentially leading to gentrification and displacement. Option (c) emphasizes historical preservation without considering modern infrastructure needs or economic viability, which might limit the district’s potential for growth and adaptation. Option (d) prioritizes technological innovation without a clear framework for its integration with social and environmental factors, potentially leading to solutions that are not equitable or ecologically sound. Therefore, the integrated approach in option (a) is the most comprehensive and aligned with sustainable development goals, reflecting the forward-thinking educational philosophy of the Polytechnic University of Chihuahua.
