Chapter 16, Problem 82P

The angular velocity of the disk is ω=10 rad/s. The radius of the disk is 0.8 m. Determine the magnitude of the velocity of point A on the disk.

The r-y coordinate system is body fixed with respect to the bar. The angle 0 (in radians) is given as a function of time by 0 = 0.1+0.08t². The a coordinate of the sleeve A (in feet) is given as a function of time by x = 3+0.06t3. Determine the velocity of the sleeve at t = 4 s relative to a nonrotating reference frame with its origin at B. (Although you are determining the velocity of A relative to a nonrotating reference frame, your answer will be expressed in components in terms of the body-fixed reference frame.)

The uniform 1,157-mm link AB slides up on frictionless rollers as shown below. At the instant shown, the link AB is vertical and the absolute velocity of point A is 19.9 m/s in the direction shown. Ignore the link thickness and roller diametres. For this configuration, 01=39 degrees and O2=25 degrees as shown. VA 01 A G Calculate the absolute velocity of the centre of mass at G. Give your answer in the form Z = 2 VGx + VGy in m/s where vGx is the horizontal component of the velocity vector (positive to the right) and VGy is the vertical component of the velocity vector (positive upwards). Round your final answer to two decimal places.

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

The wheel slips as it rolls (in the same direction as point O). If vo = 6 ft/sec and if the magnitude of the velocity of A with respect to B is 3 ft/sec, locate the instantaneous center C of zero velocity and find the magnitude of the velocity of point P. A B D 9" P 5" VO v of P = ft/sec
