Question

What er two way engineers use their understanding of ke and pe to make their designs bteer

A) Determining optimal material strength and durability
B) Balancing forces and motions in mechanical systems
C) Assessing structural stability and safety margins
D) Calculating energy efficiency and performance metrics

Answer 1

Engineers apply their knowledge of kinetic energy (KE) and potential energy (PE) by ensuring structural stability and designing energy-efficient systems, utilizing principles from physics such as energy conservation and equilibrium.

Step-by-step explanation:

Engineers utilize their understanding of kinetic energy (KE) and potential energy (PE) in various ways to improve their designs and solve engineering problems. Two key ways they do this are:

• Assessing structural stability and safety margins: This involves analyzing how structures can remain in a stable equilibrium under various forces, such as wind and earthquakes. Ensuring the net external force and torque are zero is essential for stable building designs.
• Calculating energy efficiency and performance metrics: Engineers use principles of thermodynamics and energy conservation to design more efficient systems. Understanding how energy transfers and is conserved within systems helps in creating energy-efficient designs such as alternative fuel vehicles or eco-friendly buildings.

Both of these applications require a thorough understanding of physics, particularly the concepts of energy, to ensure that mechanical components and systems are both safe and efficient.
