The disc with a radius of 257 mm is connected to a frictionless stationary pivot O via a lightweight rod of length 1.33 metres (top view shown below). The rocket provides a constant 22.5 N force and remains perpendicular to the connecting rod. Assume the disc slides on a frictionless surface. Calculate the magnitude of the reaction force at pivot 04 seconds after the rocket was fired. Give your answer in newtons and round the final answer to two decimal places.
