Note the angle and find the coefficient of friction. For this purpose we have found the Normal force and sliding. Then, by using formula of coefficient of friction we found the value, which was approximately 0.18 at 10°, 20° and 30°.

Experiment to Determine the Coefficient of Friction.
Material Angle θ Coefficient Tan θ
Brass 15.1 0.27
Nylon 12.3 0.22
Ferado 13.7 0.24
This experiment has two aims. The first aim of this experiment is to determine the coefficient of friction on an inclined plane by using various materials tray. Secondly, to verify that the force have already found which were required to move a body on an inclined plane. We have provided apparatus to do this experiment that include stainless steel plane, load hanger, different weights and 4 trays of different materials such as aluminium, brass, nylon and ferado. Firstly, we place tray at the middle of plane and apply weight on weight hanger until tray starts to move. Note the angle and find the coefficient of friction. For this purpose we have found the Normal force and sliding. Then, by using formula of coefficient of friction we found the value, which was approximately 0.18 at 10°, 20° and 30°. Nevertheless, the additional 10N weight was added but the friction coefficient but the angle will remain same. The experiment was taken by under good circumstances. However, errors can be reduce by overlapping the mistake that was take place in this experiment. This experiment could be done exactly the same as international standard if the following conditions apply on it.
How do you find the coefficient of friction experimentally?
To measure the static coefficient of friction, you take the value of the force just as the object starts to move. Doing the same experiment with sliding or kinetic friction, you want to take your reading when the object is sliding at an even velocity. Otherwise, you will be adding in acceleration force effects
