Chapter 16, Problem 13P

The disk has an angular velocity of 8 rad/s and is increasing at the rate of 5 rad/s' about its Z- axis and the yoke AB has a constant angular velocity w = 3 rad/s about its shaft as shown. Simultaneously the entire assembly revolves about the fixed X-axis with constant velocity o, = 5 rad/s. Determine the velocity and acceleration of point F on the disc for an instant shown in the figure. Also find angular velocity and angular acceleration of the disc. 20 cm 15. 30 cm 30 cm 30 cm N 20 cm

Please solve this using scalar analysis by getting the scalar components at the x and y direction and not by using i-j-k

At the instant represented, the velocity of point A of the 1.89-m bar is 3.6 m/s to the right. Determine the speed VB of point B and the magnitude of the angular velocity w of the bar. The diameter of the small end wheels may be neglected. 0.46 m- 67 B 1.89 m Answers: m/s VB rad/s

The wheel of radius r = - 4 ft rolls without slipping on the horizontal surface. At the instant shown, 3.7 rad/sec, ao : 8.8 ft/sec², and 0 = 60°. Determine the vectors of the accelerations of points A, B, and C on the wheel. (σ = 63.6i +8.8 ft/sec², dB = 43.8i - 43.0j ft/sec², ac = 54.8 ft/sec²) W= = y ω B r απ Ꮎ × A C

Bar BC rotates about the fixed pivot B with constant angular velocity w = 3 rad/s. Pin A is fixed to bar OA, which rotates about a fixed axis through point O, and is engaged in the slot of member BC. If at the instant presented, 0 = 35°, calculate the angular velocity and angular acceleration of bar OA for this instant. Use d = 0.3 m and l = 0.6 m. (wOA = 3.94 rad/s CW, ao₁ = 3.64 rad/s² CCW) d A l B Ꮎ 3

The disks roll on the plane surface without slippage. The left disk rotates at 2 rad/s in the clockwise direction. Determine the angular velocity of the bar. Enter an answer in radians per second up to the second decimal place. Note that the counterclockwise direction is the positive rotation. 2 rad/s 3 ft 1 ft 1 ft
