Asked by Reagan

A machine with v.r of 5 requires 1000No of work to raise a load of 500N through a vertical distance of 1.5. ( a ) find the efficiency of the machine. (B) calculate it's mechanical advantage
Answered by Reagan
How can that be solved
Answered by henry2,
a. eff. = Wo/Wi = (500*1.5)/1000 =

b. Vr = de/dl = 5,
de/1.5 = 5,
de = 7.5 m. = distance moved by the Effort(E).

E * de = 1000 J.
E * 7.5 = 1000,
E = 133.3 N. = Effort.
M.A. = L/E = 500/133.3 =
