Solve the below problem:
Q: A beam ABC is supported by a pin connection at A and by rollers at B. A 120-kg block placed on the end of the beam causes a static deflection of 15 mm at C. Assuming that the support at A undergoes a vertical periodic displacement d = dm sin ωft where dm = 10mm and ωf = 18rad/s, and the support at B does not move, determine the maximum acceleration of the block at C. Neglect the weight of the beam and assume that the block does not leave the beam.
