Chapter 16, Problem 141P

(b) The disk cam is controlled by the 5" slotted arm AB through a pin P fixed on the disk. If at the instant shown, 0 = 60°, 0 = -0.1 rad/s, and 6 = -0.2 rad/s², find the angular velocity w and the angular acceleration a of the disk at the instant. O is at the 9 o'clock position P is at the 6 o'clock position. II 발 20 O C F5 F6 B 3" A F7 R=4" 8 F8 F9 prt sc F10 home F11 end F12

At the instant shown on the right, the wheel rotates about the fixed axis C with clockwise angular velocity of w = 8 rad/s and a clockwise angular acceleration of 16rad/s^2. The point B, located at the distance of r = 15cm form the center is attached to the bar AB, which has a length of L = 50cm. The slider A is constrained to move horizontally. What is the speed and acceleration of the slider A?

In the mechanism shown in the figure, the C pin attached to the element no. can slide. Calculate the angular velocity and angular acceleration of slide number 3. Elements 2 and 3 Calculate the accelerations of the centers of gravity. θ.2 rad/s=20 θ..2 rad/s 2 = 35  r2 = 920mm d2 = 550mm s3 = 450mm d4 = 350mm

Bar OC rotates with a clockwise angular velocity woc = 2.9 rad/s and a counterclockwise angular acceleration đoc = 1.5 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 = 415 mm, d = 320 mm, e = 37°. A B d aoc Answers: rad/s W = 4.71 i -34.6 rad/s?
