(a) Using a single fixed pulley: The effort required is equal to the weight of the load, which is 100 N.
(b) Using a single movable pulley: The effort required is half of the weight of the load, which is 50 N.
(c) Combination pulley system made up of 5 pulleys: The mechanical advantage of a pulley system is equal to the number of strands of the rope supporting the load, which in this case is 5. Therefore, the effort required is 1/5th of the weight of the load, which is 20 N.
(d) The combination pulley system made up of 5 pulleys is the best pulley to use in this case because it requires the least effort to lift the load. It provides a mechanical advantage of 5, which reduces the effort required to lift the load. The single movable pulley also provides a mechanical advantage of 2, but it is not as efficient as the combination pulley system. The single fixed pulley does not provide any mechanical advantage and requires the same effort as the weight of the load.
1. Determine the effort required to lift a load of 100 N using:
(a) Using a single fixed pulley
(b) A single movable pulley
(c) Combination pulley system made up of 5 pulleys (d) Compare your results, which is the best pulley to use in this case? Why ?
