Question # 1

Why can a body not rotate about its centre of gravity under the action of its weight?

Ans 1: As we know that the centre of gravity is that point at which the whole weight of the body acts.In this case, the line of action of force (weight) passes the pivot point (centre of gravity).Therefore, moment arm is zero.As a result torque is also zero.

Question # 1

The gravitational Force acting on a satellite is always directed towards the centre of the earth?

Ans 1: We known that the torque depends upon the moments arm and applied force. Mathematically we have
T = r*F
As we have given that the gravitational force acting on a satellite is directed towards the centre of the earth. As for central force, the moment arm is zero r= 0 so T = o*F = 0
T= 0
Eq (2) shows that the torque produced by gravitational force acting on a satellite zero

Question # 1

Explain why do buses and heavy trucks have large steering wheels ?

Ans 1: We know that the magnitude of torque depends upon the moment arm and applied force T = r* f
Show that to produce greater torque with a less applied force, the value of moment arm 'r' must be taken as larger due to greater torque, we can turn the heavy trucks and buses have large steering wheels to produce greater torque and to make the drive more easy.
