Applied Mechanics

Q1: The mechanical advantage of an ideal machine is 100. For moving the local through 2 m, the effort moves through

A 0.02 m

B 2.5 m

C 20 m.

D 2 m

ANS:A - 0.02 m

Given the machine is ideal means efficiency is 100%.

Therefore, MA = VR.
100 = Y/X.

Y = Distance Moved By Effort.
X = Distance move By load.

Therefore 100 = 2/x.
X = 2/100.
= 0.02.
