3. The angular velocity of bar OA is constant at 2 rad/sec clockwise. Find the acceleration of the block at Point B.

1. At the time the crank AC is at 30° the collar is 6" from point A and crank BC is horizontal. The crank AC is rotating at 3 rad/s counter clockwise. The collar C is free to slide on the frictionless crank AC. What is the total acceleration of point C? 3" В A

A portion of a steam locomotive is shown below. If the locomotive is moving to the right at a constant speed of 45 mph, (a) what is the linear and angular velocity of point B, and (b) what is the linear and angular acceleration of point B, given that the wheels are 50 inches in diameter, length AC = 10 in, length AD = 55 in, and B is half way between A and D.

The instant shown, bar AB has an angular velocity of 6.5 rad/s and an angular acceleration of 4 rad/s², both clockwise. 200 mm B 75 mm D 175 mm 100 mm A E Determine the angular acceleration of bar BD by using the vector approach. (You must provide an answer before moving to the next part.) The angular acceleration of bar BD is rad/s² clockwise.
