Figure Q1 shows a disc OA and a rod CD is linked by a connecting rod AB. The disc is pinned at O and the rod CD is pinned at C. At the instant shown, the disc is rotating with an angular velocity, OA=5rad/s. Determine: a. The velocity of point A,VA, point B,VB and point D,vD, b. The angular velocity of rodCD,CD and connecting rodAB,AB. Given: OA=0.5m,AB=1.5m, and CB=BD=0.6m (6 marks) SOLUTIONS/ PENYELESAIAN VA=2.5m/sAB=0.833rad/sVB=2.16m/s30.CVO=1.66m/s30CWCO=1.38rad/s QUESTION 2 At the instant shown in the Figure Q2, collar C is moving upwards with a velocity of 4m/s, accelerating at a rate of 10m/s2. Disc OA with radius, r=0.3m is rotating with angular velocity, Disc=8rad/s about point O and angular velocity of member ABC,ABC at 10rad/s(). Determine: a. angular acceleration of disc OA,OA b. angular acceleration of member ABC,ABC (6 marks) SOLUTIONS/ PENYELESAIAN OA=391.96rad/s2
