In the case of a single fixed pulley, state whether the load moves in the direction of effort or opposite to effort?
Single Fixed Pulley:
In a single fixed pulley, if the effort moves by a distance x downwards, by what height is the load raised upwards ?
A boy uses a single movable pulley to lift a load of 50kgf to some height. Another boy uses a single fixed pulley to lift the same load to the same height. The ratio of efforts on single movable pulley to efforts on single fixed pulley is,
A single fixed pulley makes the task easier by changing the direction of the effort.
For a single fixed pulley, an effort of 400N is required for a load of 300N. If the effort is moved by 30cm then calculate the efficiency of the pulley & energy that is used in overcoming friction.
