What is the maximum column load in kips that could be placed on a 4-ft square temporary footing on a sand for which the standard resistance is about N=15 and the water table is at the surface? A factor of safety of 2 is to be maintained against bearing failure.
Determine: a) the height of the water, with respect to the base of each standpipe, and b) the effective stress at the depth of each standpipe, at the following times:
a 10.0 inch long 10-guage wire of yellow brass (E=105 GPa) is subjected to an axial tensile force of 400 lbs. Find the normal sress and deformation in the wire. A 10-guage wire has a diameter of 2.588 mm.
If the Greenshields model describes the relationship between speed and density on the highway, the jam density of the highway is 112 veh/mi, and the mean free speed is 64.5 mph,
What type of exercise takes place in a classroom setting arranged to look like an emergency operations center or in an actual emergency operations center, and involves simulation using written, telephone, and radio messaging.
State the full name of the section of SOLAS that sets out the minimum standards for the training and competence of crew members and describe how the surveyor would go about checking that a vessel had the necessary number of qualified staff.
The total flow then moves to a point W on the traction drive two metres off the ground, and travels through a nine millimetre diameter conduit. Ignoring all friction and minor losses, determine the pressures at points H and W.
Field tests have shown that the Horton equation best describes the composite roughness of the channel. Find the capacity of the main channel and the lateral extent of the floodplains for a 100-year flow of 1590m^3/s.
A thin-walled cylindrical tank of radius r is subjected simultaneously to internal pressure p and a compressive force P through rigid end plates. Determine the magnitude of force P to produce pure shear in the cylindrical wall.
At point 2, the velocity and pressure are 14 ft/s and 23 psi. Determine at which of these two points the elevation is higher. Calculate the height difference. (Assume the sp ecific gravity of butane is 0.6 and that the butane is at a temperature o..
