Industrial Maintenance Mid Term Chapter 3 2026 – Mechanical Systems and
Maintenance Study Guide
potential energy - correct answer ✔✔ stored energy
kinetic energy - correct answer ✔✔ energy of motion
Force - correct answer ✔✔ Anything that changes or tends to change the states of rest or
motion of the body
work - correct answer ✔✔ Movement of a object by a force to a specific distance
Torque - correct answer ✔✔ rotational force, twist
Lever - correct answer ✔✔ a simple machine that consists of a bar that pivots at a fixed point
called a fulcrum
Power - correct answer ✔✔ The rate of doing work or using energy
Inclined plane - correct answer ✔✔ Simple machine consisting of a cylinder rotating freely in its
axis which uses a belt, rope or chain
horse power (hp) - correct answer ✔✔ Unit of power equal to 746 W or 550ft-lbs
Area - correct answer ✔✔ Number of unit squares equal to the surface
Pressure - correct answer ✔✔ Force per unit area.
, A wheel and axle - correct answer ✔✔ Simple machine consisting of a wheel and an axle fixed
together along the same axis
Wedge - correct answer ✔✔ Simple machine that converts force applied to its blunt end into
force that is perpendicular to its slopes surface
Screw - correct answer ✔✔ Simple machine consisting of a continuous spiral on a cylinder
Conduction - correct answer ✔✔ Heat transfer that occurs when heat is passed from molecule
to molecule through a material
Heat transfer - correct answer ✔✔ Transferred from one substance to another when a
temperature difference exists between the two substances
Efficiency - correct answer ✔✔ Measure of a devices useful output energy compared to its input
energy
A substance - correct answer ✔✔ Can be in a solid, liquid, or gas state
Inertia - correct answer ✔✔ Tendency of a physical body to persist in its state of rest or
uninform motion until acted upon by an external force
Heat - correct answer ✔✔ Composed of atoms and molecules that are in a constant state of
motion
Temperature - correct answer ✔✔ The measurement of the intensity of heat
