Q1 Consider the system of pulleys and mass shown in Figure 1. Pulley D is fixed. MA = 150kg, MB = 50 kg, the angle of incline 0 = 45°. Coefficient of friction between the inclined plane and the object A is u= 0.3. a) Write down the three assumptions that are normally used to simplify the solution of constrained kinetic problems of this type. Briefly explain the consequence of each assumption. [3] b) Draw the free-body diagrams for objects A and B. [5] c) The system is released from rest, determine the acceleration of object A and the tension in the cable attached to object B. [7] d) What should the minimum change be in the mass of object B to reverse the direction of motion ? [5] D С B A Кө
