c) If the motor draws in the cable with an acceleration of 4.0 m/s², determine the reactions at the supports A and B. The beam has a uniform mass of 31 kg/m, and the crate has a mass of 250 kg. Neglect the mass of the motor and pulleys. Hint: First find the tension in the cable (carefully) using Newton's 2nd Law then solve for the reactions at the support using static equilibrium methods.
