The load was lifted using an inclined plane. In this case, the useful work was equal to 160 J and the total 200 J Determine the efficiency of the inclined plane.
Initial data: Ap (useful work when lifting a load using an inclined plane) = 160 J; Az (full (expended) work when lifting a load) = 200 J.
The efficiency of an inclined plane can be determined using the formula: η = Ap / Az * 100%.
Let’s calculate the efficiency: η = 160/200 * 100% = 80%.
Answer: The efficiency of the inclined plane is 80%.
