A cantilevered W12x136 (ASTM-A36) steel member beam is 18 ft in length. If a concentrated load of 12 kips is applied at a point 6.25 ft from the beam's free end, use the superposition technique to find:
A) The deflection at the free end caused by the beam's own weight.
B) The deflection of the free end caused by the concentrated load.
C) The total deflection due to the two weights.
After compaction the void ratio is reduced to 0.60. Determine: (a) Dry and moist unit weights before and after compaction (b) Degree of saturation after compaction.
To avoid submergence the crest of the weir must be at least 0.05 m above the downstream water depth. Here we can assume that the depth downstream is equal to the normal depth. To simplify calculations we will assume that Cd = 0.7 Water depth over the..
An egual-tangent sag vertical curve is designed with the PVC at station 109+00 and elevation 950 ft, the PVI at station 110+77 and elevation 947.34 ft, and the low point at station 110+50. Determine the design speed of the curve.
A train starts from rest at station A and accelerates at 0.5m/s^2 for 60s. Afterwards it travels with a constant velocity for 25min. It then decelerates at 1 m/s^2 until it is brought to rest at station B. Determine the distance between the stations
write computer code using Matlab that emoloyes the nelder and mead simplex method to solve the welded-beam design (benchmark problem
A hydraulic jump is observed to occur in a channel with a mild slope at a flow rate of 20cfs/ft. If the depth before the jump is 1 ft, determine the depth after the jump.
A trapezoidal channel is to be designed to carry a discharge of 250 cfs at a normal depth of 3.5 ft. The channel is running on a slope of 0.005 ft/ft and the side slopes can be no steeper than 2.5 H on 1 V.
Calculate the time of flight of the bolt from the ceiling tothe floor. Assume that the elevator continues its upward acceleration. (Use a frame reference fixed with respect to the elevatorshaft)
how do you find the force ratio equation to determine the maximum total load that can be applied to a truss?nbspgiven a
Benefits associated with a project are $10,000 forever starting in year 1. The costs are $20,000 in year 0 and $20,000 in year 3. What is the B/C ratio at i=12% per year. First determine present worth for benefit and cost, respectively.
A rectangular culvert 4 feet x 6 feet is running full and discharging 3,500 cfm. There is no friction loss. Find the velocity in fps. The culvert empties into a 10 ft wide culvert and the velocity reduces to 0.6 fps. How deep is the water level in th..
Assume that a gallon of gas contains 114,000 BTUs of energy and that a brilliant engineer has created an 80 percent efficient solar cell. Find the area (in square smoots and in square feet) that an array of these solar cells
