Question

If \(\mu_k = 0.2\), \(\mu_s = 0.3\), crate weight = 500 lb and the horizontal force P = 160 lb, and knowing that there is impending downward motion, determine: 28. the Free Body diagram, 29. the force (lb) acting normal to the incline, \(F_N\), 30. the frictional reaction force (lb), \(F_s\), between the crate and the incline.

If = 0.2, = 0.3, crate weight = 500 lb and the horizontal force P = 160 lb, and knowing that there is impending downward motion, determine:
28. the Free Body diagram,
29. the force (lb) acting normal to the incline, FN,
30. the frictional reaction force (lb), Fs, between the crate and the incline.

Step 1

The FBD should include the following forces: - Weight of the crate acting vertically downward (500 lb) - Normal force acting perpendicular to the incline (FN) - Frictional force acting parallel to the incline (Fs) - Applied force (P) acting parallel to the Show more…
