Two blocks A and B have a weight of 10 lb and 6 lb, respectively. They are resting on the incline for which the coefficients of static friction are A = 0.15 and B = 0.25. Determine the angle which will cause motion of one of the blocks. What is the friction force under each of the blocks when this occurs? The spring has a stiffness of k = 2 lb-ft and is originally unstretched. A k = 2lb/ft wwwwww B
