Question 7 (aligned to content from section 7.3 of the course): A support block is acted upon by two forces as shown. Knowing that the coefficient of friction between the block and the incline are s = 0.35 and = 0.25, determine: a) The force P for which motion of the block up the incline is impending b) The friction force when the block is moving up c) The smallest force P required to prevent the block from sliding down Solution P 25 800 N
