1.What are the different types of stress that a structural element could be subjected to at different cases of loading?
2.In order for a shower head to produce a 2.5 gpm flow for 120?F water, what pressure (psi) is needed at the hot water tank if the shower head elevation above the hot water tank is 28 ft? The pipe diameter is 1-in, and assume that the shower head has an effective diameter of 2-in. Neglect friction.
A rectangular channel carries a flow of 10 cfs/ft of width. Plot a curve of specific energy vs depth. Compute the minimum value of specific energy and the critical depth. What are the alternative depths for Es = 5.0
An embankment for a highway 30m wide & 1.5m in a compacted thickness is to be constructed from a sandy trucked from a borrow pit. the water contenet of the sandy soil in the borrow pit is 15%& its void ratio is 0.69.
a 150 kg mass is suspended by wires from two hooks. the lengths of the wires have been adjusted so that the wires are each 50º from horizontal. assume that the mass of the wires is negligible.
A level is set up midway between two wood stakes that are about 300 feet apart. The rod reading on Stake A is 9.65 ft and the reading on stake B is 4.23 ft. The level is then set up 6 feet in front of stake B.
The fixture AC is designed with a screw adjustment to regulate the height of the 900 N load supported by the roller at A. The screw bears against a smooth surface at B. Determine the reaction forces at points B and C. Neglect the weight of the fix..
On a certain highway a -6% grade meets a +2% grade at station 70 + 00, elevation 550.97 ft. An equal tangent vertical curve, 800 ft. long, is to be installed to connect these two grades.
A -4% grade and a 0% grade meeting at sta. 24 + 40 and elevation 2421.54 ft are joined by an 800-ft vertical curve. The curve passes under an overpass at sta. 25+00.
Find the angular velocity and angular acceleration needed to keep the prisoner in the beam of the spot light at the moment when the prisoner is 4000 ft away from the spot light.
