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 motion of an oscillating crank is defined by the relation Θ=6sin(πt/4)-sin3 where 'Θ' is expressed in radians and 't' in seconds. Determine the angular displacement, the angular velocity, and the angular acceleration of the crank when (a) t=0s, (b)=2s. (c) Draw the graph of the angular displacement, angular velocity and angular acceleration from t=0 to t =2. (d) solve what time will the crank starts to decelerate? Hint: at the same time the angular acceleration becomes zero before becoming (-).

At the instant shown, the shaft and plate rotate with an angular velocity of 14 rad/s and angular acceleration of 7 rad/s?. Determine the speed and acceleration of point D, located in the corner of the board right now. Express the result in the form of a Cartesian vector. 0.6 m 0.2 m 0.4 m 0.3 m 0.3 m 0.4 m
