PROBLEM 4: In the figure shown, block A weighs 300 kN and block B is also 300 kN. Force P is applied to push the blocks forward. The coefficient of friction μ = 0.20 for both A and B. The blocks are connected by a solid strut attached to each block with frictionless pins. (a) what is the force on the strut, in KN? (b) what is the reaction at B, in kN? (c) what is the value of P, in kN, to prevent forward motion? 30° 60° B
