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
Correct Answer: Option C
Explanation
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.
