MAE 1351 EXAM 2 Questions and Answers | Latest Update | 2024/2025 | Graded A+ How can understanding friction improve engineering designs? Understanding friction helps engineers design systems that minimize energy loss and wear, ensuring better performance and longevity of mechanical components. What is the role of a load path in structural engineering? A load path is the route through which loads travel through a structure to the foundation, ensuring that forces are effectively transferred and balanced throughout the design. How does the concept of elasticity affect material selection? Elasticity describes a material's ability to return to its original shape after deformation, guiding engineers in selecting materials that will withstand specific loads without permanent changes. What factors influence the thermal expansion of materials? Thermal expansion is influenced by temperature changes, material properties, and the physical dimensions of the object, affecting how structures respond to heat variations. 2 Why is understanding torque important in mechanical systems? Understanding torque is essential for designing mechanisms that involve rotation, as it determines the effectiveness of forces applied at various distances from the pivot point. How do vibrations impact the design of mechanical systems? Vibrations can lead to fatigue and failure in components; therefore, understanding their effects helps engineers design systems that can either dampen or control these vibrations. What is the significance of the stress-strain curve in materials science? The stress-strain curve illustrates a material's response to applied stress, providing critical information on its yield strength, ultimate tensile strength, and ductility. How does buoyancy affect the design of vessels and submarines? Buoyancy plays a crucial role in ensuring that vessels and submarines can float or submerge, guiding designs to balance weight and displacement for stability. What are the implications of thermodynamic cycles in engine design? 3 Thermodynamic cycles describe the processes that engines undergo, influencing efficiency and power output, which are vital for optimizing performance in thermal systems. What role does CAD software play in modern engineering design? Computer-Aided Design (CAD) software allows engineers to create precise drawings and simulations, improving accuracy, efficiency, and collaboration in design processes. How does the concept of redundancy contribute to safety
