3 ft 130 B 2 ft At the instant shown, the velocity of the slider block at joint Cis downwards whereas the link AB, has an angular velocity of 2 rad/s about point A. a) Read the entire question and list all the required and given data. (2 Marks) b) Explain the following: (3 Marks) i. Why the velocity at point A is zero? ii. Why the velocity at point B would be acting vertically downward? c) Draw the kinematic diagram of the link AB showing: (5 Marks) i. xyz reference axis system (with i, j, k) ii. Velocity at point B ii. Relative position vector TB/A iv. Angular velocity WA of link BC about point Cand its rotation sense. d) Write each of the vectors of the kinetic diagram in their cartesian vector form. (5 Marks) e) Use the relative velocity equation on link AB to estimate the velocity of point B. (5 Marks) Ans: 4 ft/s Draw the kinematic diagram of the link BC showing: (5 Marks) i. xyz reference axis system (with i, j, k) ii. Velocity at point B ii. Velocity at point C iv. Relative position vector rc/B V. Angular velocity vector wg of link BC about point B, and its rotation sense. Draw a sketch to resolve the rc/B into its components. Also write it in cartesian vector form. (5 Marks) h) Use the relative velocity equation on link BC to estimate the velocity of slider block C and the angular velocity of link BC about point B. (5 Marks) Ans: o rad/s, 4 ft/s.
