Transcribed Image Text:Force P is applied to the end of a rope being used to hold the 50-lb block on the 20° incline.
The coefficient of static friction between the block and the incline is u. = 0.30. Determine
the largest value of P for which the block is in equilibrium and will not begin to move up
the incline when 0 = 15°.
Hs
= 0.30
20°
The solution to this problem requires a free-body diagram of the block, and a sketch of the
coordinate system used. Use the components of the forces with EF = 0 and EF, = 0 to
y
apply ΣF=0.
