The tide gate opens automatically when the tide water at B subsides, allowing the marsh at A to drain. For the water level h = 4 m, determine the horizontal reaction at the smooth stop C. The gate has a width of 2 m.

A concrete gravity dam has the following data: Maximum water level = 300.00 m Bed level = 220.00 m R.L top of dam = 304.00 m %3D The d/s slope of 0.67:1 starts at RL of 295.00 m U/s face is vertical. Center line of the drainage gallery = 8.0 m from u/s face. Consider only weight of dam, water pressure and uplift pressure. Calculate only the normal stresses at the toe and heel of the dam, assuming 100% uplift pressure at the h eel and 50% at the gallery and zero at the toe.

The channel is subjected to a shear of V = 20 kip. (a) Determine the shear flow at point A. 1.5 im (b) Determine the shear flow at point B. (c) Determine the maximum shear flow in the channel. 4 in. A 8 in. 1.5 in. B 13 in. 1.5 in.
