Question 2: The motion of the 5kg Mass E is governed by the 100Nm moment M exerted on link AB that is pin connected to link BC and link OD which is attached to a cable at point D as shown in figure 2. The masses of the slender links AB, BC and OD are 2kg, 5kg and 8kg respectively. The system is initially at rest when a 100Nm moment is applied on link AB. (a) Identify the components, write down their expected motion at the instant shown including degree of freedom and draw the chosen coordinate system. [4 marks] (b) Draw the corresponding free body diagram and kinetic diagram of each component. [10 marks] (c) Write down the equations of motion and kinematic relationships between the acceleration of each and every component [10 marks] (d) Find the initial acceleration of mass E and tension in the cable [6 marks] D 0.5m Moment M 0.5m 0.5m с B A 0.25m Mass E
