A body is placed on a rough inclined plane having inclination θ greater than angle of repose ϕ. What is the minimum force required to take the body up on inclined plane?

Solution

Given angle of inclination $straight theta$ is greater than angle of repose $straight ϕ$ .
So, minimum force required to take the body upto inclined plane = $space space mg left parenthesis sinθ plus cosθ space tanϕ right parenthesis$
