In which direction the force must be applied, when a single pulley is used with a mechanical advantage greater than one?
In which direction does the force need to be applied when single pulley is used with a mechanical advantage greater than1 ? How can u change the direction of force applied without altering its ma
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.
