The 16-ft-long cord is attached to the pin at C and passes over the two pulleys at A and D. The pulley at A is attached to the smooth collar that travels along the vertical rod. When SB 6 ft, the end of the cord at B is pulled downwards with a velocity of 4 ft/s and is given an acceleration of 3 ft/s2. Determine the acceleration of the collar at this instant. 3 ft 3 ft T SB SA B

Replace the force system by an equivalent resultant force and couple moment at point P.

2)There is a roller at A and pin support at B. Label the tip of the cantilever "E." The "C" and "D" labels can be disregarded. Use an x-coordinate that starts at the tip of the cantilever and goes to the right. 4 kN/m A B -1.5 m -1.5 m -1.5 m- -1.5m-
