The wheel in the figure rotates clockwise with a constant angular velocity of 120 rpm. The pin D is fixed to the wheel at a point 125 mm from its center and slides along the guide in the arm AB. Determine:

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

The mechanism shown below is a marin steering gear called a Raphson slide. The link AB is the tiller, and the link CD is the actuating rod. If the velocity of CD is constant 10 inches per minut to the right. Calculate anguler velocity of tiller. 300° B D

At the instant shown in (Figure 1), rod AB has an angular velocity WAB = 2.2 rad/s and an angular acceleration AB = 10 rad/s². The collar at C is pin-connected to CD and slides over AB. Part A Determine the angular velocity of rod CD at this instant. Express your answer in radians per second to three significant figures. Enter positive value if the direction of velocity is counterclockwise and negative value if the direction of velocity is clockwise. Figure 60° WAB αAB 0.75 m Do 0.5 m 1 of 1 ΜΕ ΑΣΦ.
