Question

Which of the following disciplines provides study of relative motion between the parts of a machine?

(a) theory of machines

(b) applied mechanics

(c) kinematics

(d) kinetics

This question was addressed to me in an online interview.

This intriguing question originated from Relation Between Linear Motion and Angular Motion topic in chapter Kinematics & Kinetics of Motion of Machine Kinematics

Answer 1

The correct answer is (c) kinematics

To elaborate: The study of inertia forces arising from the combined effect of the mass and motion of the parts is called kinetics.

The study of relative motion between the parts of a machine is called kinematics.

The study of the relative motion between the parts of a machine and the forces acting on the parts is called theory of machines.
