7.3 A hydraulic lift has a mechanical advantage of 6. If the load weighs 780 N, calculate the effort required to lift the weight. Provide your answer in Newtons.​

Effort = 120 Newton

Explanation:

Given the following data;

Mechanical advantage = 6

Load = 780 N

To find the effort required to lift the weight;

Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.

Mathematically, the mechanical advantage is given by the formula;

Making effort the subject of formula;

Substituting into the formula, we have;

Effort = 120 Newton.
