Question

An effort of 1960 N is required just to move a certain
body up inclined plane of angle 15°, the force acting
parallel to the plane. If the angle of inclination of the
plane is made 20°, the effort required, again applied
parallel to the plane, is found to be 2254 N. Find the
weight of the body and the coefficient of friction.
