If the mechanical advantage of a machine is 4. What is its ratio for LOAD to EFFORT?
  • A.
    4:01
  • B.
    1:04
  • C.
    5:01
  • D.
    2:01
Correct Answer: Option A
Explanation

Mechanical advantage (M.A) of a machine is the ratio of its load to effort
Mathematically
Mechanical advantage (M.A) = Load (L) ÷ Effort (E)
In symbol M.A = L/E
Note:Mechanical (advantages has no S.I unit)
If M.A = 4 then,
L/E = 4/1
The ratio of load to effort = 4 : 1 respectively
