MAE 1351 EXAM 1 Questions and
Answers | Latest Version | 2024/2025 |
Rated A+

What is the principle of conservation of energy in mechanical systems?


✔✔The principle of conservation of energy states that energy cannot be created or destroyed; it

can only be transformed from one form to another within a mechanical system.




How do you define a scalar quantity in physics?


✔✔A scalar quantity is defined as a physical quantity that has magnitude but no direction, such

as temperature or mass.




What is the significance of the center of mass in mechanics?


✔✔The center of mass is significant in mechanics as it represents the point where the total mass

of a system can be considered to be concentrated for analysis of translational motion.




What is the formula for calculating work done in a mechanical context?


✔✔The formula for calculating work done is Work = Force × Distance × cos(θ), where θ is the

angle between the force and the direction of motion.

, Explain the concept of static equilibrium.


✔✔Static equilibrium occurs when an object is at rest and the sum of all forces and moments

acting on it is zero, resulting in no acceleration.




What is Hooke's Law, and how is it applied?


✔✔Hooke's Law states that the force exerted by a spring is directly proportional to the

displacement from its equilibrium position, applied in the formula F = kx, where k is the spring

constant and x is the displacement.




How do you determine the moment of inertia for a solid cylinder?


✔✔The moment of inertia for a solid cylinder is determined using the formula I = (1/2) m r²,

where m is the mass and r is the radius of the cylinder.




What is the difference between kinetic energy and potential energy?


✔✔Kinetic energy is the energy of an object in motion, calculated as KE = (1/2) mv², while

potential energy is the stored energy based on an object's position, such as gravitational potential

energy given by PE = mgh.
