At the instant shown, gear A is rotating with a constant angular velocity of _A = 6 rad/s. Determine the largest angular velocity of gear B and the maximum speed of point C.

Arm ABCD is printed at B and undergoes reciprocating motion such that  = (0.3 sin 4t) rad, where t is measured in seconds and the argument for the sine is in radiaus. Determine the largest speed of point A during the motion and the magnitude of the acceleration of point D at this instant.

Due to an engine failure, the missile is rotating at  = 3 rad/s, while its mass center G is moving upward at 200 ft/s. Determine the magnitude of the velocity of its nose B at this instant.

The sphere starts from rest at  = 0 and rotates with an angular acceleration of  = (4) rad/s², where  is measured in radians. Determine the magnitudes of the velocity and acceleration of point P on the sphere at the instant  = 6 rad.

If the block at C is moving downward at 4 ft/s, determine the angular velocity of bar AB at the instant shown.

The mechanism is used to convert the constant circular motion of rod AB into translating motion of rod CD. Compute the velocity and acceleration of CD for any angle  of AB.

The rotation of link AB creates an oscillating movement of gear F. If AB has an angular velocity of _AB = 8 rad/s, determine the angular velocity of gear F at the instant shown. Gear E is a part of arm CD and pinned at D to a fixed point.

As the cord unravels from the wheel's inner hub, the wheel is rotating at  = 2 rad/s at the instant shown. Determine the magnitudes of the velocities of point A and B.
