A pulley system has a velocity ratio 3 and an efficiency of 80%. Draw a labelled diagram of this pulley system. Calculate :
(a) the mechanical advantage of the system, and
(b) the effort required to raise a load of 300 N.
The given figure shows an arrangement of moving pulleys.
If the effort applied at the free end of the string is E; what is the mechanical advantage of the system of pulleys?
A pulley system has a velocity ratio 3 and an efficiency of 80%. Calculate the mechanical advantage of the system.
A pulley system has velocity ratio of 3. If it efficiency is 75%, calculate its mechanical advantage. [Assume 1 kgf = 10N, 1 gf = 1000 dynes]
