A canal lock is 6 m wide and has two vertical gates which make an angle of 120â—¦ with each other. The depths of water on the two sides of the gates are 9 m and 2.7 m respectively. Each gate is supported on two hinges, the lower one being 600 mm above the bottom of the lock. Neglecting the weight of the gates themselves, calculate the thrust between the gates and the height of the upper hinges if the forces on them are to be half those on the lower hinges.
