Pully Diagram

They are typically used for hauling and lifting loads but can also be used to apply tension within a system such as in a tensioned line or tyrolean.
Pully diagram. When you need to lift a heavy weight a pulley can make the job easier. For example if your small pulley is 80mm diameter and spins at 1000 rpm and you need to find the second pulley size to spin it at 400 rpm enter pulley1 80 pulley 1 rpm 1000 pulley 2 rpm 400 and hit calculate to find the second pulley diameter.

Pulley systems are used to provide us with a mechanical advantage where the amount of input effort is multiplied to exert greater forces on a load. The force at the point of load. This page explains the basic principles of.
Basically all that a pulley is is a wheel spinning around an axle to aid the motion of a belt. A pulley is one of the physic s six non motorized simple machines in this case one that reduces either the effort necessary to lift a load or the direction in which the force needs to be applied in order to move the load or it may do both things. The luff tackle adds a fixed pulley rove to disadvantage the tension in the rope remains w 3 yielding an advantage of three.
You must decide if you will use a double pulley system with one sheave the roller in a. A belt or rope that runs inside the groove of the wheel. In this diagram the pulley attached to the weight actually consists of two separate pulleys on the same shaft as shown on the right.
The rope is pulled on the effort side and the weight being lifted is on the right hand side called the load. Reduce the force needed as well as the direction. The pulley is one of the six simple machines.
In a simple pulley on one end of the rope or belt is a load l and the other end is left free to apply force f. The mechanical advantage of the gun tackle can be increased by interchanging the fixed and moving blocks so the rope is attached to the moving block and the rope is pulled in the direction of the lifted load. In general a single pulley is useful as it allows the labourer shown right to lift the weight without bending his back.
