Question

10. A block and tackle system has the velocity ratio 3.
Draw a labelled diagram of the system indicating the
points of application and the directions of load L and
effort E. A man can exert a pull of 200 kgf. (a) What
is the maximum load he can raise with this pulley
system if its efficiency is 60% ? (b) If the effort end
moves a distance 60 cm, what distance does the load
move ?​
