Chapter 8, Problem 30P
Two blocks A and B have a weight of 10 Ib and 6 Ib, respectively. They are resting on the incline for which the coefficients of static friction are. μA = 0.15 and, μB = 0.25. Determine the incline angle θ for which both blocks begin to slide. Also find the required stretch or compression in the connecting spring for this to occur. The spring has a stiffness of, k = 2Ib/ft.
