Trig Q - MEDAL

A uniform log of length L is inclined 30 degrees from the horizontal when supported by a frictionless rock located 0.6L from its left end. The mass of the log is 200 kg. An engineer with a mass of 53.5 kg walks along the log from the left to the right until the log is balanced horizontally. How far from the left end of log is the engineer when the log is horizontal?
