Which of the following motions will be produced by a pair of equal, opposite and non-collinear parallel forces acting on a body?
A
Oscillatory
B
Random
C
Rotational
D
Translational
E
Vibratory
Verified Correct Answer: C.
Physical Principles & Numerical Solution
A couple consists of two equal and opposite forces acting at a separation, so that net force becomes zero. When a couple acts on a body it rotates the body but does not produce any translational motion. Hence, only rotational motion is produced.
