3 Problem A hydraulic cylinder rotates around point O at a constant rate 60 deg/s and the cylinder length L is decreasing at a constant rate L = -150 mm/s. Determine the magnitude of velocity and acceleration of the endpoint B when L = 125 mm. Assume that d = 375 mm. d 0 B

2. The gear A on the drive shaft of an outboard motor has a radius of ½ inch while the meshed pinion gear on B has a radius of 1% inches. If the drive starts from rest and is accelerated at a constant a = 200 rad/s², what is the speed, tangential acceleration, and normal acceleration at point P on the propeller after 3 seconds. 2.20 in

A pendulum with a cord of length r = 1.05 m swings in a vertical plane (see figure). When the pendulum is in the two horizontal positions 0 = 90° and 0 = 270°, its speed is 4.95 m/s. a (a) Find the magnitude of the radial acceleration (in m/s2) for these positions. m/s2 (b) Find the magnitude of the tangential acceleration (in m/s?) for these positions. m/s? (c) Draw a vector diagram to determine the direction of the total acceleration for these two positions.
