An overhead projector is required to display content on transparencies. A transparency is a thin sheet of plastic in which light is reflected upon to display content.The light source emits light towards the transparency and then the image is displayed on the wall. Usually, this light source comes from below and lights upward and so the content is depicted above or overhead.

Zielflug [23.3K]

Answer:

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;

$M.A = \frac {Load}{Effort}$

Making effort the subject of formula;

$Effort = \frac {Load}{M.A}$

Substituting into the formula, we have;

$Effort = \frac {720}{6}$

Effort = 120 Newton.
