Question

a lever used to lift heavy box as an effort arm of 4m and a load arm of 0.8 meter what is the mechnical advantage of the lever? ​

Answer 1

Answer:

mechanical advantage is that...

Explanation:

it will increase the torque of lifting even if we apply less force..

torque =ř×f

so more we increase the distance from the lifting....more it will get easier to lift the box even with comparatively less force.

Answer 2

Answer:

fort arm = 4 m

Load arm = 0.8 m

We know that,

M.A. = Effort arm length/Load arm length

M.A. = 4 m/0.8 m

M.A. = 5
