Why is the pulley less than 100% efficient?

It is important to remember that NO pulley system is 100% efficient. This is due to friction of the ropes against the pulley wheels and the friction of the bearings of the pulley wheels as they rotate. This type of pulley arrangement will always have the same mechanical advantage and velocity ratio.
