Explain why a single fixed pulley is used despite no gain in mechanical advantage.
What is the ideal mechanical advantage of a single fixed pulley ? Can it be used as a force multiplier?
State whether the following statements are true or false by writing T or F. (a) The velocity ratio of a single fixed pulley is always more than 1. (b) The velocity ratio of a single movable pulley is always 2. (c) The velocity ratio of a combination of n movable pulleys with a fixed pulley is always 2^(n) . (d) The velocity ratio of a block and tackle system is always equal to the number of strands of the tackle supporting the load.
A movable pulley is used as:
A single fixed pulley and a movable pulley both are separately used to lift a load of 50 kgf to the same height. Compare the efforts applied
State four differences between a single fixed pulley and a single movable pulley.
In a single fixed pulley, if the effort moves by a distance x downwards, by what height is the load raised upwards ?
