1.A dam has a parabolic shape z/zo = (x/xo)2 as shown below, with xo = 10 ft and zo = 24 ft. The fluid is water, gamma = 62.4 lbf/ft3, and atmospheric pressure may be omitted. Compute the forces FH and FV on the dam and their line of action. The width of the dam is 50 ft.

2.A flat bar of cross section 20mm by 70mm elongates 4.0mm in a length of 2.0m as a result of axial load. If the elastic modulus is 199x106 kN/m2 and Poisson's ratio is 0.25 for the material, find the axial load and the total change in each cross sectional dimension.
