Mr. d needs to create a lever with a mechanical advantage of 0.4. if he is going to
apply his force 2 meters from the fulcrum, how far away must his load be from the
fulcrum to get the correct mechanical advantage?

The distance of load from fulcrum is 5 m.

Explanation:

Given:

Mechanical advantage, MA = 0.4

Distance of force from fulcrum is,

Distance of load from fulcrum is,

We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.

So, Mechanical advantage is given as:

Therefore, the distance of load from fulcrum is 5 m.

i think it's 35 meters
