Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.

Water flows in a rectangular open channel that is 10m wide, at a depth of 2.5m. The Manning roughness coefficient of the sides of the channel is 0.015 and the bottom of the channel is 0.010 . Calculate the equivalent roughness coefficient by using Horton –Einstein approach.
The bed of a corrugated channel, with Manning’s coeffcient n =0.019 s/m^1/3 drops 25 m every 1500 m. The channel has a semi-circular cross section with total width of W = 10 m (i.e. radius of the semi-circle is 5 m). 1. Given that the stream has a water depth of h = 2.5 m, find the flow rate in the stream 2. A concrete divider with the same Manning’s coeffcient was installed at the middle of the stream. Given that the total flow rate in the stream stays the same, would the water depth in the stream change as a result of the divider? If so, would it increase or decrease? Would the stream velocity change? If so, would it increase or decrease? You may assume the thickness of the divider to be negligible.
