Answer 2

Answer:

Answer :

Mechanical advantage of the machine, M.A. = 5

Explanation :

Given :

Load to be lifted by the machine, L = 50 kgf

Effort applied to life the load by the machine, E = 20 kgf

To find :

Mechanical advantage of the machine, M.A. = ?

Knowledge required :

Formula for mechanical advantage of a machine :

⠀⠀⠀⠀⠀⠀⠀⠀⠀M.A. = L/E⠀

Where,

M.A. = Mechanical advantage of the machine.

L = Load to be lifted by the machine

E = Effort applied on the load by the machine.

Solution :

By using the formula for mechanical advantage of a machine and substituting the values in it, we get :

⠀⠀=> M.A. = L/E

⠀⠀=> M.A. = 50/10

⠀⠀=> M.A. = 5

⠀⠀⠀⠀⠀⠀∴ M.A. = 5

Hence the mechanical advantage of the machine is 5.
