Question

when a rigid body is subjected to a non concurrent force system it undergoes
a) Both translational and rotational motion
b) None of the above
c) translational
d) rotational​

Answer 1

Answer:

c) translational motion

Answer 2

When the system experiences non concurrent force ,it undergoes option (d )Rotational motion

Explanation:

Concurrent force system:  In this system, all the forces pass through a common point i.e. line of action of all the forces applied meet at a single point.

By resolving the vector components of Force, we can see that it has the possibility of undergoing translation motion. Also by solving the equations for torque, we see that it can also undergo rotational motion.

Non concurrent force system: In this system, two or more forces whose magnitudes are equal but act in opposite directions with a common line of action are applied on the system.

Therefore in this type of system, translational motion is not possible and only rotational motion is possible.

Hence option (d) correct.
