Cylinder A is moving downward with a velocity of 8 m/s when the brake is suddenly applied to the drum. The cylinder moves 11 m downward before coming to rest. Assume uniformly accelerated motion. 250 mm A Determine the angular acceleration of the drum. (You must provide an answer before moving to the next part.) The angular acceleration of the drum is |rad/s2 0.

Problem 3 At the instant when 0 = 36.87°, the body of the satellite rotates with angular velocity of wi = 1.5 rad/s and angular acceleration of 2 rad/s. Simultaneously, each solar panel rotates with angular velocity of w2 = 2 rad/s and angular acceleration of 1 rad/s, both measured relative to the body of the satellite. • Determine the angular velocity vector wsp of the solar panel. Determine the angular acceleration vector asp of the solar panel. • Determine the position vector rao of point B.

Please help. This problem involves finding the angular velocity and angular acceleration. Thank you.

A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 590 rpm, and disk A is at rest. Disk B is known to stop in 69 seconds, decelerating constantly. However, instead of waiting for both disks to be at rest before bringing them into contact, disk A is given a constant angular acceleration of 3.5 rad/s2 counterclockwise. a) Determine the time, in seconds, in which both disks can be brought into contact without slipping. A 2.5 in. Fuente: Beer, 11th Ed. B 3 in. b) Determine the angular velocity of disk A, in rpm, when contact is made without slipping. c) Determine the angular velocity of disk B, in rpm, when contact is made without slipping.

Q1: A wheel has an initial clockwise angular velocity of 1Orad/s and a constant angular acceleration of 3rad/s?. Determine the number of revolutions it must undergo to acquire a clockwise angular velocity of 15 rad/s. What time is required? Ans.: 3.32 rev, t = 1.67 sec. Q2: The angular position of a radial line in a rotating disk is given by the clockwise angle 0 = 2t3 – 3t2 + 4 where 0 is in radians and t is in seconds. Calculate the angular displacement A0 of the disk during the interval in which its angular acceleration increases from 42 rad/s? to 66 rad/s?. %3D - Ans.: A0 = 244 rad

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 550 rpm, and disk A is at rest. It is known that disk B will coast to rest in 65 s. However, rather than waiting until both disks are at rest to bring them together, disk A is given a constant angular acceleration of 3 rad/s² counterclockwise. A 2.5 in. B 3 in. Determine at what time the disks can be brought together if they are not to slip. (You must provide an answer before moving to the next part.) The disks can be brought together at t= S.

consider the articulated robot arm shown. the motor at joint A (driving arm AB) has a constant counterclockwise angular velocity of 2 rad/s and the motor at joint B (driving arm BC) has a clockwise angular velocity of 3 rad/s that decreasing at a rate of 1 rad/s. if arm AB has length 1.7m and arm BC has length 2.5 m, determine the acceleration of joint C at the instant pictured. the answer should be 15.95i-13.88jm/s-. 30 2nd axis 45° 1st axis P4.3-3 4-71

Two friction discs A and B will come into contact, without slipping, when the angular velocity of disc A is 320 rpm counterclockwise. Disk A starts from rest at t = 0 and has a constant angular acceleration with magnitude a. Disk B starts from rest at time t = 4 s and has a constant angular acceleration in a clockwise direction, also with a magnitude a.
