The wheel in the figure below rolls without slipping with the constant clockwise angular velocity ω0=1.6rad/s. Calculate the angular velocity of bar AB and the velocity of the slider B when the mechanism is in the position shown. Use the Instantaneous center of velocity for velocities

The elements of a power hacksaw are shown in Figure 2. The saw blade ismounted in a frame that slides along the horizontal guide. If the motor turns the flywheel at a constant counter-clockwise speed of 60 r.p.m. Make use of vector diagram to calculate: the acceleration of the blade for the position where angle ? = 90o The corresponding angular acceleration of the link AB.

Name The wheel, having a two-foot radius rolls without slipping at constant speed on the ground. The motion of peg B, which is attached to the wheel, causes the slotted bar to rotate about its fixed axis. In the position shown, the angle of the bar is 0 = 60°. Problem #2 Determine the angular velocity of the wheel. Determine the angular velocity of the slotted bar. Determine the sliding velocity of peg B relative to the slotted bar. Determine the angular acceleration of the slotted bar. Determine the sliding acceleration peg B relative to the slotted bar. 10 B. 45° 20 ft/sec

Bar OC rotates with a clockwise angular velocity woc = 5.3 rad/s and a counterclockwise angular acceleration doc = 4.6 rad/s². The bar OC is a slotted member which accommodates the pin A attached to the sector. Determine the angular velocity w and the angular acceleration a of the sector. The angular velocity and the angular acceleration are positive if counterclockwise, negative if clockwise. Assume OA = 500 mm, d = 385 mm, 0 = 21°. Answers: W = B a = i i d aoc rad/s rad/s² @oc
