Two weights A and B are connected by a string passing over an ideal pulley as shown in Fig. NP 17.2. If the weights A and B are 60 kN and 400 kN, respectively. then determine the pull to the applied at A tangential to the incline in such a way that it causes A to impend downward. Take the coefficient of friction between all contact surfaces as 0.20. >ideal pulley 30 60° Fig. NP 17.2
