Question on: JAMB Physics - 2015
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
Ask EduPadi AI for a detailed answer
Correct Option: A
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
