A force, applied to a body at a given point, produces a
torque about another point O. The magnitude of the torque about
O is equal to the product of the force and the perpendicular
distance of the force from O.
A body is in static equilibrium if (a) the net force on the
body is zero, and (b) the net torque on the body is zero.
In solving problems on static equilibrium, simplification
is obtained if a judicious choice is made of the point O, about
which torques are calculated.
