Question
As seen in the figure, the block on an inclined plane is lifting from 0 0 with two degrees
increment in each step. (0, = 0, 0 =2, 02 = 4, ..) Until which degree can we increase
the angle without any slipping between the block and the inclined plane?
For condition of F > F, the block continues to hang on the inclined plane. Otherwise, it starts
to slip.
F, = W + sin8(rad),
Fy = W+ cosa(rad)
F = F, + u,
u = 0.50,
W = 100 N
