Question

The figure above shows an H-like object that is free to rotate (in the plane of the page) about the fixed axis shown. A force is applied at each of the six locations shown, one location at a time. In each case the force is the same size and is always straight right. Rank the locations based on the magnitude of the torque that will result when the force is applied at that location. Ties are possible. Use the symbols > and = to indicate your ranking, listing any that are equal in alphabetical order.
LARGEST TORQUE to SMALLEST TORQUE

Explanation / Answer

We know that

T=r * F sin(theta)

In A & D, r(distance from axis) is maximum but angle at A is close to 90 degree. Max torque will be produced at A then D.

At B and F it will be same and at C and E it will be same, but angle at B and F is more close to 90 degree.

The correct order is,

A>D>B=F>C=E
