Consider a simply supported beam of length L. The beam experiences a parabolically varying distributed load that varies from 0 at the left support, to a maximum w at midspan, and back to 0 at the right support. The beam has stiffness properties EI. Give a mathematical equation that gives the value of the distributed load intensity at any distance z along the beam in terms of w, L and z. Draw the SFD and BMD of the beam, giving the maximum values in terms of w and L. What is the midspan deflection of the beam in terms of EI and w and L.

A trapezoidal channel is to be designed through a silty clay alluvium on a slope of 0.0035 ft/ft. The angle of repose of the material is 35° and the Manning coefficient is 0.025. If the channel is to be designed to carry a maximum discharge of 700 cfs at a depth of 4.9 ft, determine if rip-rap will be required, and, if so, compute the stone size for both the bed and sides.

kips y LL= 300 kips). The
element is braced, so LX= 22 ft and LY= 12 ft. The end support
conditions are:
a) (Fixed/pinned) and it is specified to use A572 gr. 60. (verify
slenderness and
local buckling)
b) (Fixed/Fixed) and you must use A-36

You are part of the water supply engineering team of your council. Your team is working on a certain part of cast iron piping of a water distribution system involving a parallel section. Both parallel pipes have a diameter of 30 cm, and the flow is fully turbulent. One of the branches (pipe A) is 1000 m long while the other branch (pipe B) is 3000 m long. If the flow rate through pipe A is 0.4 m3/s, determine the flow rate through pipe B and the head loss in pipe B. Disregard minor losses. Consider the water temperature to be 15°C. Assume that the flow is fully turbulent (i.e. the friction factor is independent of Reynolds number).
