Given:-
☛Efforts = 8kgf
☛Loads = 100kgf
☛Distance through efforts = 50cm
☛Distance through loads = 3cm
Find:-
☛a)velocity ratio
☛b) mechanical advantage
☛c)percentage efficiency of the machine
Solution:-
☛a) velocity ratio-
where, = Distance through effort moves
= distance through load moves
velocity ratio = 50:3
☛b) Mechanical advantage-
Mechanical advantage= 12.5
☛c)Percentage efficiency of the machine-
Percentage efficiency of the machine is 75.03%
