Amover loads a crate onto a truck bed 1.6m from the street using a ramp that is 4.6m long. what is a mechanical advantage?

Mechanical advantage = 2.875

Explanation:

Given:

A diagram is shown below for the above scenario.

Length of ramp (Effort arm) = 4.6 m

Height of truck bed ( Resistance length) = 1.6 m

Mechanical advantage (MA) is the ratio of effort arm and resistance length.

So, mechanical advantage is given as,

the plateau is likely to turn into a desert do to corrosion.
