ENGINEERING MECHANICAL TERMS
QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
Machine - ANSWER A device that is capable of transforming energy to provide a designed type/direction
of motion and force.
Mechanism - ANSWER An assembly of moving parts involved in or responsible for taking an input motion
or force and transforming it to an output motion or force.
Kinematics - ANSWER A branch of engineering mechanics that studies motion without regard to the
force or mass of the things being moved.
Dynamics - ANSWER The branch of classical mechanics that is concerned with the effects of forces on the
motion of objects.
Lever - ANSWER A machine consisting of a beam or rigid structure with a fixed hinge or fulcrum.
Pulley - ANSWER A wheel on an axle that is designed to support movement and change of direction of a
cable or belt along its circumference.
Wheel & Axle - ANSWER A simple machine generally consisting of a wheel attached to an axle so that
motion and/or force can be transmitted from one to the other.
Inclined Plane - ANSWER A flat supporting surface tilted at an angle, with one end higher than the other,
used as an aid for raising or lowering a load.
Wedge - ANSWER A triangular shaped tool used to separate two objects or portions of an object, lift up
an object, or hold an object in place.
Screw - ANSWER An inclined plane wrapped around a cylinder, a mechanism that converts rotational
motion to linear motion, and a torque (rotational force) to a linear force.
