Question

2. An effort force of 20 N is used to lift a load of 60 N by a machine. Calculate the mechanical advantage of the machine 3​

Answer 1

Explanation:

Provided that:

Effort force = 20 Newton

Load = 60 Newton

To calculate:

Mechanical advantage

Solution:

Mechanical advantage = 3

Using concept:

Mechanical advantage formula

Using formula:

{\small{\underline{\boxed{\pmb{\sf{MA \: = \dfrac{l}{e}}}}}}}

MA=

e

l

MA=

e

l

Where, MA denotes mechanical advantage, l denotes load and e denotes effort.

Required solution:

\begin{gathered}{\sf{:\implies Mechanical \: advantage \: = \dfrac{Load}{Effort}}}\\\end{gathered}

:⟹Mechanicaladvantage=

Effort

Load

\begin{gathered}{\sf{:\implies MA \: = \dfrac{l}{e}}}\\\end{gathered}

:⟹MA=

e

l

\begin{gathered}{\sf{:\implies MA \: = \dfrac{60}{20}}}\\\end{gathered}

:⟹MA=

20

60

\begin{gathered}{\sf{:\implies MA \: = \dfrac{6}{2}}}\\\end{gathered}

:⟹MA=

2

6

{\sf{:\implies MA \: = 3}}:⟹MA=3

Henceforth, mechanical advantage is 3.
