Transcribed Image Text:

A force P acts on a brick block having a mass of m with the block resting on a rough inclined concrete. The coefficients of static and kinetic friction between the block and the incline are uS and µk, respectively. Using the following parameters values: e = 32.5º, mass of the block = 20 kg, uS = 0.6 and uk is ignored in this case. 3.1 Determine the minimum force P required to hold the block in equilibrium. 3.2 Determine the minimum force P required to initiate motion of the block up the incline.
