The "Great Swing" at a country fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. Each arm supports a seat suspended from a 5.00m long rod, the upper end which is fastened to the arms at a point of 3.00m from the central shaft.
Find the time of one revolution of the swing if the rod supporting the seat makes an angle of 30 degrees.
