Question

The mechanical advantage of a machine is 5. Calculate the load to be lifted using an effort of 40N.​

Answer 1

$\sf Given \: \begin {cases} & \sf { Mechanical \: advantage \: of \: a \: machine = \: 5 } \\ & \sf{ Effort = 40 N} \end {cases}$

⠀⠀⠀⠀

To find :-

⠀⠀⠀⠀

• $\sf Load = ??$

⠀⠀⠀⠀

Explanation :-

⠀⠀⠀⠀

$\bigstar\:{\underline{\sf What \: is \:mechanical \: advantage \: ??}}$

⠀⠀⠀⠀

• The Ratio of the load to the Effort

⠀⠀⠀⠀

⠀⠀⠀⠀

$\star\;{\boxed{\sf{\pink{Mechanical \: advantage = \dfrac{Load}{Effort} }}}}$

⠀⠀⠀⠀

$:\implies\sf 5 = \dfrac{Load}{40 N}$

⠀⠀⠀⠀

$:\implies\sf Load = 5 \times 40 N$

⠀⠀⠀⠀

$: \implies \sf Load = 200 N$

⠀⠀⠀⠀

$:\implies{\underline{\boxed{\frak{\purple{Load = 200 N }}}}}\;\bigstar$

⠀⠀⠀⠀

$\therefore\:{\underline{\sf{The \; load \; to \; be \:lifted \; using \; the \; machine \: of \: M.A. \: 5 \: is \bf{200 N}.}}}$

Answer 2

Answer:

Given :-

• The mechanical advantage of a machine is 5. An effort of a machine is 40 N.

To Find :-

• What is the load to be lifted.

Formula Used :-

As we know that,

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

From this formula we can get load formula,

$\bigstar \: \boxed{\sf{Load =\: Mechanical\: Advantage \times Effort}}$

Solution :-

Given :

• Mechanical Advantage = 5
• Effort = 40 N

According to the question by using the formula we get,

$\implies$ $\sf Load =\: 5 \times 40\: N$

$\implies$ $\sf\bold{\red{Load =\: 200\: N}}$

$\therefore$ The load to be lifted is 200 N .
