A light rod

AB

of length

1.0\,\text{m}

is hinged at end

A

and is kept horizontal. A downward force of

20\,\text{N}

is applied at a point

0.30\,\text{m}

from

A

, while an upward force of

15\,\text{N}

is applied at end

B

. Calculate the net torque about the hinge and state whether the resulting rotation is clockwise or anticlockwise.
