Chapter A screw is a simple mechanical device that multiplies effort. The force that you apply to the screw is called the effort force, whereas the force that applies to the object in response to the effort force is called the output force. The spiral ridges are the threads of the screw. The distance from head to thread is called the pitch. The diagram shows how turning the head of the screw can cause the screw to move into the object. The distance around the head of the screw is related to the distance the effort moves. The distance through which the output moves corresponds to the pitch of the screw. *ridge: A violin creates tension in its strings and gives each of them an equilibrium shape: a straight line. A tight violin string can be viewed as composed of many individual pieces that are connected in a chain as in the above two figures. When the string is straight, as in Figure 1, its tension is uniform, and the two outward forces on a given piece sum to zero; they have equal magnitudes and point in opposite directions. With no net forces acting on its pieces, the string is in equilibrium. But when the string is curved, as in Figure 2, the outward forces on its pieces no longer sum to zero. Although the string's uniform tension still gives those outward forces equal magnitudes, they now point in slightly different directions, and each piece experiences a zero net force. The net forces on its pieces are restoring forces, which will cause the string to vibrate and thus make sounds. *equilibrium: **magnitude: 140
