In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw. Guide A starts from rest with pin P at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 110 mm/s at the halfway point of its vertical displacement. The guide then decelerates at a constant rate and comes to a stop with pin Pat the uppermost point in the circular slot. Determine the n-and t-components of acceleration of pin Ponce the pin has traveled 20° around the slot from the starting position. 22% Answers: an 285 mm i mm/s² mm/s²

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.
The x- and y-motions of guides A and B with right-angle slots control the curvilinear motion of the connecting pin P, which slides in both slots. For a short interval, the motions are governed by x - 12+0.55t² and y-16-0.57t³, where x and y are in millimeters and tis in seconds. Calculate the magnitudes of the velocity v and acceleration a of the pin for t-2.5 s. Sketch the direction of the path and indicate its curvature for this instant.

In the mechanism shown in Figure Q3, the inclined rod AC is pinned to a collar that can slide along the fixed vertical rod DE. Rod AC also slides within another collar that is attached to a fixed pin at B. If the collar, A, slides upwards at a constant velocity of 1ms2, determine at the instant shown:- (a) the angular velocity of the rod AC, (b) the angular acceleration of the rod AC. E 100mm A.

In the figure, Pulley A, rotating at 20 rad/s, controls the motion of Pulley B. The motor of pulley A is cut off, and friction eventually brings the pulleys to a stop with an angular acceleration of α = -2.5t rad/s2. If there is no slippage, determine: a. The angular velocity of B with respect to time b. The angular displacement of B during the deceleration c. The acceleration of point C with respect to time
A yoke, alternatively known as a control wheel or a control column, is a device used for piloting some fixed-wing aircraft. The pilot uses the yoke to control the attitude of the plane, usually in both pitch and roll. Rotating the control wheel controls the ailerons and the roll axis. A little plane named A is ready to land at a speed of 78 miles per hour. What angle must the pilot steer the aero plane to such that the absolute velocity is parallel to the runway if the airplane is facing a constant side headwind of speed vw = 21 mi/hr. as it is shown? So, what was the touchdown speed?

The rear wheel of a car moving to the right has a diameter of 26" (66.04 cm) and an angular speed N of 1000 rev/min (rpm) on an icy road. The instantaneous center of zero velocity is 10 cm above the point of contact with the road. Determine the velocity V of the car and the slipping velocity V, of the tire on the ice? 26 inç 1000 d/dk
