single pulley
A Defensive Core Skill A single pulley is a basic mechanical tool that is marked by two major characteristics through its simplicity and efficiency. These days, it consists of a wheel on a supported frame, called the Sheave (see above). It is hard work to lift a big stone into a cart. But with the main function of the single pulley--changing direction in which force is applied to move load--this becomes easier. And in all its technological features, it is a durable design that can take tensile loads significant enough to do harm; the equipment might be made from a variety of materials to suit different environments. This pulley has numerous applications in several industries, ranging from construction and manufacturing to shipping and agriculture. for tasks that require high work effort—culminating in the movement of heavy objects.
