احصل على السعرالحصول على الاقتباسThe lever is probably the most commonly used simple machine. A lever is a rigid bar or solid object that is used to transfer force. With a pivot, the lever can be used to change the force that is applied (effort), alter the direction, and change the distance of movement. Effort, a pivot, and a load are three features that are common in every lever.
