Answer:

The amount of effort needed to move the box is 187.5 N

Explanation:

weight of the box = load moved by the ramp, L = 750 N

mechanical advantage of the ramp, MA = 4

effort needed to move the box, E = ?

Mechanical advantage is given as = Load / Effort

Effort = Load / Mechanical advantage

Effort = 750 / 4

Effort = 187.5 N

Therefore, the amount of effort needed to move the box on to the truck using a ramp is 187.5 N
