Question

the mechanical advantage of a Lever used to it is used to raise a load of 15 KGF what is the effort needed ​

Answer 1

Answer:

Question to be asked :-

the mechanical advantage of a Lever is 2 used to it is used to raise a load of 15 KGF what is the effort needed

Given :-

Mechanical Advantage = 2

Load = 15 KGF

To Find :-

Effort

Solution :-

As we know that

$\huge \bf \: Effort = \dfrac{ Load}{Mechanical\: Advantage}$

Effort = 15/2

Effort = 7.5 KGF

Therefore,

Effort to be applied is 7.5 KGF

Answer 2

$\huge \mathbb{ \red {★᭄ꦿ᭄An} \pink{s}\purple{S} \blue {w} \orange{e} \green{R★᭄ꦿ᭄}}$

Explanation:

The mechanical advantage of a lever can be increased by increasing the effort arm or reducing the load arm.

Given,

Mechanical advantage = 2

$Load = 15 Kgf$

Mechanical advantage =

Load Mechanical advantage

$Load\ Effort$

$Effort  = load / Machinal \ advantage$

$=15 /2$

$= 7.5 kgf$
