Working Principle of Pulley

Home Pulley Working Principle of Pulley As Pulley is a type of simple machine it helps to reverse the direction of lifting force. When one end of the rope is pulled downwards, the load on the other end of the rope is pulled upward. Therefore, the direction of force is changed from downwards to upwards. Pulley can work on one, two and four …

Write the principle of working of an electric motor.

Complete step-by-step answer: The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil. The following are the parts of an electric motor:
