Question
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 μ = 0.16 and μ = 0.25. Determine the incline angle 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 = 2.0 lb/ft. (Figure 1)
