Question

Whal are the position, welocity and acceleration of the obiecf afer 1.00 seconds? ivi) (5 marks) 300 rad/s 13. 600 A 50 mm 170 mm Consider the slider-crank mechanism above. The crank rotates at a constant angular velocity of 300 rad/second. (0 What is the velocity of B relative to A. V? (4 marks) () Draw a half scale diagram of the mechanism itself Show on the diagram the line of the velocity of B relative to A (1 mark) (@i) On the same diagram show the line of the velocity of C relative to B. Va ov) On the same diagram show the line of the velocity of C relative to A. () Recaling the vector sum -+cle velocity vector diagram using what you know (1 mark) (1 mark) a construct a scale velocity vector diagram using what you know 165 these velocities and, from this diagram measure the size of the velocity of C relative to B V (4 marks) What is the acceleration of the slider. C in ts housing relative to A? () (9 marks) 14 A car has an acceleration a, that is a function of time : a()-3r.2.
