Plz anwer fast 2. A pulley system has five pulleys in all, 2 in the movable
block and three in fixed block, such that effort is applied
in the upward direction and a load of 60 kgf is attached to
the movable block.
(a) What is the velocity ratio of pulley system?
(b) Assuming pulley system an ideal one, what is the
mechanical advantage?
(c) What is the magnitude of effort applied?
(d) Ifthe pulley system is not ideal but is 75% effcient,
what is the effort required?
