Document Summary
Question: calculate the increase in bolt tension (2 bottles each at a and b) due to filling the tank with fresh water to this depth. Assume that there is no change in the gasket pressure between the cover plate and the tank, so that the force, due to the water pressure is resistant entirely by the increase in bolt tension. Note that the plate on the right covers a 300 x 300 mm hole in the tank. Calculations: ta = change in bolt force of 1 bolt at line a, tb = change in bolt force of 1 bolt at line b. Fbd at equilibrium o: ra= 2. 45 * 0. 3 * 0. 3 = 2. 221kn, rb = (6. 4 * 2. 45 / 2) (0. 3)(0. 3) = 0. 132 kn, sum of moments about point a = 0 = (0. 221)(0. 2) + (0. 132)(0. 25) = (2 ta)(0. 4)
