Question
Q4.) The 12 kg block A and 10 kg block B are pinned to a rod having negligible mass and resting on horizontal surfaces. A horizontal force P is applied to the rod at end C increasing gradually from zero until motion first begins. a) If the coefficient of static friction between both blocks and each surface is μ = 0.45, determine the value for P at which point motion first begins and describe the motion that occurs in a few brief words. b) If the coefficient of static friction between both blocks and each surface is μ = 0.6, determine the value for P at which point motion first begins and describe the motion that occurs in a few brief words. (Hint: Consider drawing the system as one FBD for this analysis and treat each block as a particle with negligible dimensions) 100 mm 200 mm с Bo 10 kg 25° A 12 kg 12 kg
