Task id16429
A body of mass m = 20 kg is held on an inclined plane by a rope, which is tied to a dynamometer mounted above the plane. The dynamometer shows 113 N. The plane is inclined to the horizontal at an angle a = 30°. Find the angle b between the direction of the rope and the inclined plane and the reaction force of the inclined plane N. Neglect friction.
