The 428-kg uniform beam is subjected to the three external loads shown. Compute the vertical reaction (N) at the support point O if P = 4202 N, Q = 3387 N, T = 40694 Nm, x = 1.14 m, y = 1.53 m, and z...

The 428-kg uniform beam is subjected to the three external loads shown. Compute the vertical reaction (N) at the support point O if P = 4202 N, Q = 3387 N, T = 40694 Nm, x = 1.14 m, y = 1.53 m, and z = 1.46 m and the system is in equilibrium.Positive values are to the right, up, and counterclockwise. Round off only on the final answer expressed in 3 decimal places.
