Question

calculate the mechanical advantage of a machine to lift load of 240N by applying an effort of 20N​

Answer 1

AnswEr :

• The mechanical advantage of a machine is 12.

Explanation :

We are given with force/load of the machine as well as effort to overcome the force of the machine, that is,

• Load on the machine = 240N.
• Effort on the machine = 20N.

We are supposed to calculate the mechanical advantage of a machine.

Given that the mechanical advantage of a machine to lift load of 240N by applying an effort of 20N.

We know that, if we are given with the load on the machine and effort to overcome the force of the machine, we have the required formula, that is,

The machine advantage is the ratio of load to effort.

i.e., Machine advantage = Load/Effort

or, MA = L/E

Where we have values as :

• MA = unknown.
• L = 240N.
• E = 20N.

By using the required formula and substituting their values in the formula, we get :

→ MA = 240/20

→ MA = 24/2

→ MA = 12

Hence, the mechanical advantage of a machine is 12.

Answer 2

Answer:

Given :-

• A machine to lift load of 240N by applying an effort of 20 N.

To Find :-

• What is the mechanical advantage of a machine.

Formula Used :-

$\clubsuit$ Mechanical Advantage Formula :

$\mapsto \sf\boxed{\bold{\pink{Mechanical\: Advantage =\: \dfrac{Load}{Effort}}}}$

Solution :-

Given :

$\bigstar\: \: \bf{Load_{(Machine)} =\: 240N}$

$\bigstar\: \: \bf{Effort_{(Machine)} =\: 20N}$

According to the question by using the formula we get,

$\longrightarrow \sf Mechanical\: Advantage =\: \dfrac{Load}{Effort}$

$\longrightarrow \sf Mechanical\: Advantage =\: \dfrac{\cancel{240}}{\cancel{20}}$

$\longrightarrow \sf Mechanical\: Advantage =\: \dfrac{12\cancel{0}}{1\cancel{0}}$

$\longrightarrow \sf Mechanical\: Advantage =\: \dfrac{12}{1}$

$\longrightarrow \sf\bold{\red{Mechanical\: Advantage =\: 12}}$

${\small{\bold{\purple{\underline{\therefore\: The\: mechanical\: advantage\: of\: a\: machine\: is\: 12\: .}}}}}$

EXTRA INFORMATION :-

❒ Mechanical Advantage :

• Mechanical Advantage "MA" is how much the machine multiplies the effort force.
• Simple machine transfer work.

❒ Load :

• The load is the output force overcome by the machine.

❒ Effort :

• The effort is the input force applied to the machine.
