A single fixed pulley makes the task easier by changing the direction of the effort.
Hence, It's true.
In a single fixed pulley, if the effort moves by a distance x downwards, by what height is the load raised upwards ?
A single fixed pulley is used because it :
(a) ha sthe mechanical advantage greater than 1
(b) has the velocity ratio less than 1
(c) gives 100% efficiency
(d) helps to apply the effort in a convenient direction.
A single fixed pulley can change ……………… of effort.
In the case of a single fixed pulley, state whether the load moves in the direction of effort or opposite to effort?
