a.) Determine the maximum shear stress in a rectangular beam 6 in. wide and 8 in. deep produced by a shear force of 38,400 lb.
b.) For the same section and shear force conditions of part (a) above. Determine the shear stress 3 inches above the neutral axis in the beam.
(c)Determine the bending moment in a rectangular beam 2 in. wide and 4 in. deep, if the maximum bending stress is 20,000 psi.
(D)Due to a leak in Pump Station 1,the Alaska pipeline is shut down briefly.The pipe line is half full.Assume the pipe is welded horizontally at its midpoint.What is the tensile force on the weld per foot? Assume Ø=40”and ?oil=53.55lb/ft3.
a saturated 100 cm^3 clay sample has a natural water content of 30 percent. it is found that the shrinkage limit occurs when the water content is 19 percent. if the specific gravity of soil solids is 2.70
Calculate the acceleration in meters per secondsquared and compare to the value of the gravitational accelerationnear the Earth's surface (9.8 m/s^2)
Construction dewatering plays are very large role in the todays construction arena. Discuss the role water conditions plays in the planning and design of a temporary earth support system.
Consider the flow field where angular velocity w is equal to 2pi rad/s ( a physical frequency of 1 Hz). Is this flow field compressible or incompressible
A section view of a dam shown and water is stored at an elevation of 6 m above the base. the water flows through the dam in a concreate opening 2m high and 3 m wide. there are no losses or friction.
assume that the whole twisting moment is taken by the bone. If the humerus can withstand a shear stress Tmax=70.0 MPa, determine the maximum force the hand can apply without fracturing the humerus. The length of the forearm is 360 mm.
Knowing that G = 11.2 x10^6 psi, determine the maximum shearing stress in each shaft when a torque of T of magnitude 420kip*ft is applied to the flange indicated. And the torque T is applied to flange B.
A 1 meter diameter cylindrical mass, M, is connected to a 2 meter wide rectangular gate. The gate is to open when the water level, h, drops below 2.5 meters. Determine the required value for M. Neglect friction at the gate hinge and pulley.
A pump in a large industrial hall containing 30 liters gasoline breaks down, causing the gasoline to spill into a 3 m2 sump surrounding the pump. The liquid pool is ignited by sparks. Assume the combustion to be 70% effective and the heat loss due..
Using the Hazen-Williams approach (seecoefficient table below), find the headloss of water flowingthrough 1,000-ft of 6-ft diameter concrete pipe at a flow rate (Q)of 80 ft3/sec
One way to treat amd is to treat the metals in a holding pond. The first order rate constant is 10/day. The concentration in the water must be below 5 ppm. How long in hours will it take to reduce the concentration from 250 ppm to 5 ppm
Estimate the size of a uniform, horizontal welded-steel pipe installed to carry 14.0 ft^3/sec of water 20 degreesC. The allowable pressure loss resulting from friction is 17ft/mi of pipe length.
