Assemble the Pulley System:Thread the spool through a wire to act as the axle. Suspend the wire between two sturdy points, like chair backs or door handles. Pin Test the Pulley:Place marbles or small objects into the cup. Pull the string over the thread spool to lift the cup. Watch how...
Say, you need to lift a load weighing 100 kg with the help of a Class 1 pulley system. In this case, the effort that is applied at one end of the rope is equivalent to the force required to lift 100 kg. In case of the Class 2 pulley system, the weight is divided equally between...

In a movable pulley (see diagram on the left), a load is attached to the pulley, and both of them can move from place to place. In this type, one end of the rope is attached to a fixed point that does not move. With a movable pulley, you need less effort to lift a load. Can...
A fixed pulley is made rigid or fastened so that it cannot be moved. Contemplate (3-5 minutes) Try out the model and make observations.Observe the directions of movement in the line when the model is used to lift a load.Mark the direction of movement of the line with arrows, from the...
Apulleyis a wheel with a groove along its edge, for holding a rope or cable. Pulleys are usually used in sets designed to reduce the amount of force needed to lift a load. However, the same amount of work is necessary for the load to reach the same height as it would without the ...
