In a machine, an effort of 10 N is applied to lift a load of 100 N. What is its mechanical advantage?

Open in App

Solution

Step 1: Given data
Effort, $E = 10 N$
Load, $L = 100 N$
Mechanical advantage, $M A = ?$
Step 2: Formula used
$M A = \frac{L}{E}$ ……………………(a)
Step 3: Calculation of mechanical advantage
Substituting the given values in equation (a), we get
$M A = \frac{100 N}{10 N} M A = 10$
Hence, the mechanical advantage of the machine is equal to 10.
