Question

find the torque due to f1 , f2 and f3​

Answer 1

Explanation:

torque due to f1=(f1cos thetha)×r (component of f1 perpendicular to axis about which point of rotation is)

torque due to f2=f2×r

torque due to f3=0

formula of torque =rfsin(thetha)

or (force perpendicular to the surface × distance between area where force is applied and the axis about which system is rotating)
