Question

In Figure 3, bar AB connects with wheel A which rolls without slipping over a horizontal surface, and with slider B that moves in a vertical guide. At the instant shown, wheel A's center is moving to the right at a constant velocity of 1 m/s. Given r- 100 mm, determine, 1) angular velocity of wheel 4, ??. Use any method. (1 mark); 2) angular velocity of bar AB, coaB. Use the method of relative motion analysis. (3.5 marks); 3) angular acceleration of wheel A, ??. Use nd any method. (1 mark); a angular acceleration of bar AB, ?4BÜse the method of relative motion analysis. (4.5 marks) 4) 500 m?n 30

Explanation / Answer

Angular velocity=v/r=1/100=10 rad/s

Angular velocity of AB will be same as B

Angular acceleration=v2/r=10 rad/s
