A pulley system has velocity ratio of 4 ...

A pulley system has velocity ratio of 4 and efficiency 90%. Calculate, (i) the mechanical advantage of the system and (ii) the effort required to raise a load of 300 N by the system.

Text Solution

Verified by Experts

Efficiency = `("Mechanical advantage")/("Velocity ratio")`
`0.9=(M.A.)/(4) implies M.A.=3.6`
