A device used to lift something heavy. By using a pulley, you half the effective weight.
Rope and pulley.
A pulley is a simple machine that consists of a wheel with a groove around its circumference where a rope or belt can run. It is used to lift or move objects by applying force to the rope or belt, making work easier.
The part of a pulley where the rope lies is called the groove or the sheave. This is the part of the pulley that provides the surface for the rope to run along while the pulley rotates.
i have acquired a clothes pulley and do not know how to feed the rope through for operation
A rope goes over the wheel of a pulley and can also be threaded through the grooves to increase friction and grip. The way the rope is positioned on the pulley determines how it will interact with the load being lifted.
A pulley doesn't raise or hoist sails. A pulley is just a wheel that eases a change in direction of a rope. It is a rope that hoists or raises sails. A rope for this purpose is called a Halyard.
The rope pulled over the branch is hampered by the rope's friction over the branch. The same rope pulled over a pulley is not affected by friction as the pulley wheel will turn as the rope is pulled.
A simple pulley is a basic type of pulley that consists of a wheel with a groove around its circumference and a rope or cord that runs through the groove. It is used to change the direction of a force or to lift or lower an object.
A flagpole can be considered a simple pulley system because the rope attached to the flag acts as a type of pulley, allowing the flag to be raised and lowered by pulling on the rope. This system demonstrates how pulleys can be used to change the direction of force to make lifting and lowering objects easier.
a pulley is a wheel with a groove along with a rope or chain.
