If a load of 1000kg can just be dragged up an incline at 10 degrees to the horizontal by a force of 5kn applied in the most effective direction, what is the value offthe coefficient offriction?

The coefficient of friction is 0.34

Explanation:

It is given that,

Mass of the load, m = 1000 kg

It is dragged up an incline at 10 degrees to the horizontal by a force of 5 KN applied in the most effective direction, F = 5 × 10³ N

We need to find the coefficient of friction between the surface and the load.   From the attached figure, the load is dragged up with a force of F. A frictional force f will also act in this scenario.

So,

Since,

or  

So, the coefficient of friction is 0.34. Hence, this is the required solution.
