Question

a machine can over come 100 kgf load by applying 25 kgf force .Find its machincal advantage.​

Answer 1

Answer:

• 4 is the required answer .

Explanation:

According to the Question

It is given that,

Machine can over come 100 Kgf load by applying 25Kgf force.

Here,

• Load of machine = 100 Kgf
• Efforts applied by machine = 25 Kgf

we have to calculate its mechanical advantage .

As we know that Mechanical Advantage is defined as the ratio of forces applied to the loads and force needed to overcome the given force.

Or,

Ratio of Loads to the efforts .

It is dimensionless (unitless) quantity.

• Mechanical Advantage = Loads/Effort

by putting the value we get

→ Mechanical Advantage = 100/25

→ Mechanical Advantage = 4

• Hence, the mechanical advantage of the machine will be 4 .

Answer 2

Given,

$\color{orange}{\sf{➨ \: Load \: of \: the \: machine \: = \: 100 \: kgf }} \\ \\ \color{orange}{\sf{➨\:Effort \: applied \: by \: the \: machine \: = \: 25 \: kgf}}$

To find,

$\color{lime}{\sf{Mechanical\:advantage}}$

Solution,

$\color{purple}\sf{Mechanical\: advantage\:=\: \frac{Load}{Effort}}$

Substituting the values,

$\color{cyan}\sf{Mechanical\: advantage\:=\: \frac{100}{25}}$

$\color{blue} \sf{{\therefore \: Mechanical\: Advantage\:=\:4\:}}$

✏ Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
