40m using a lever, then,
a. What are AMA and VR of the machine
b. Calculate the Win and Wout
c. Find the amount of wasted energy
d. What is the efficiency of the machine

Answers
henry2,
a. MA = L/E = 100/60 = 5/3.
VR = De/Dl = 40/20 = 2.
b. Wi = 60*40 =
Wo = 100*20 =
c. Wi-Wo =
d e = L/EVr = 100/(60*2) = 0.833 = 83.3 %.
VR = De/Dl = 40/20 = 2.
b. Wi = 60*40 =
Wo = 100*20 =
c. Wi-Wo =
d e = L/EVr = 100/(60*2) = 0.833 = 83.3 %.
