An arc shaped beam is shown in figure 1. The arc describes an angle of 90° and has a radius of 1m. The mass of the beam is 3kg. Figure 2 shows how the arc is supported at its left hand end through a revolute joint. Initially the right-hand end is horizontally in line with the left-hand end. The right-hand end is released while the beam is at rest. The beam experiences a moment of 5 Nm in the opposite direction to the motion. Calculate the horizontal and vertical reaction forces on the pivot when the rod reaches the position where the line joining the two ends makes an angle of 45° to the horizontal. 1m 90° 45° Figure 1.
