Question

Effort- 50 kgf
Mechanical advantage - 5
load - m​

Answer 1

Answer:

REF.Image.

Length of lever = Effort arm = AE

Load arm AB = 0.1 m

Effort E = 50 kgf

Load L = 750 kgf

AE×50=750×0.1

AE=

Answer 2

$\huge\bold\pink{\underline{{Answer:-}}}$

Given that,

Load = 120 kgf

Effort = 21 kgf

We know that,

Mechanical Advantage = load/ effort

M.A= L / E

M.A= 120/21

M.A=5.7

Hence, the mechanical advantage of machine is 5.7
