A driver applies a force to the rim of a steering wheel. The force acts at an angle of 60° to the straight line joining the centre of the wheel to the point where the force is applied.
Compared with applying the same force at right angles to that line, how does the moment about the centre of the wheel change?
The moment is unchanged.
The moment is zero.
The moment is greater.
The moment is smaller.
