Question

Find the mechanical advantage of a machine which requires an effort of 40 kgf of a load 100 kgf

Answer 1

Given

• Effort = 40 kgf
• Load = 100 kgf

To Find

• The mechanical advantage

Solution

☯ Mechanical Advantage = Load/Effort

• Note that Mechanical Advantage does not have any unit

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

➞ Mechanical Advantage = Load/Effort

• Mechanical Advantage = ?
• Load = 100 kgf
• Effort = 40 kgf

➞ Ma = 100/40

➞ Ma = 2.5

∴ The mechanical advantage of the machine is 2.5

Answer 2

Answer:

Given:-

• Effort = 40 kgf

• Load = 100 kgf

To Find:-

• Mechanical Advantage of a machine

Formula used:-

• Mechanical Advantage = $\dfrac{Load}{Effort}$

Solution:-

⟾ Mechanical Advantage = $\dfrac{Load}{Effort}$

⟾ Mechanical Advantage = $\dfrac{100}{40}$

⟾ Mechanical Advantage = $\dfrac{5}{2}$

⟾ Mechanical Advantage = $2.5$

Hence, the Mechanical Advantage of the machine is 2.5.
