The 30-lb crate is being hoisted upward with a constant acceleration of 6 ft/s2. If the uniform beam AB has a weight of 200 lb, determine the components of reaction at A. Neglect the size and mass of the pulley at B.

Ax = -48.3 lb, Ay = 248.3 lb, MA = 258 lb-ft CCW
Ax = -48.3 lb, Ay = 248.3 lb, MA = 741 lb-ft CCW
Ax = -35.6 lb, Ay = 236 lb, MA = 678 lb-ft CCW
Ax = -30.0 lb, Ay = 230 lb, MA = 650 lb-ft CCW
