Define the problem of calculating the stresses in an elastic half space ?

W A 3ft long bar with a 1in x 1in cross section is subjected to a 14,153lb tensile load. What is the tensile stress in ksi? Answer to two decimal places. Type your answer...

Two 20 mm thick slabs are joined by a 10 mm thick slab as shown in the figure. The bolts used as fasteners are A325 bolts with a diameter of 5/8" with threads outside the shear plane. The quality of the steel plate is BJ 37. Calculate the design tensile resistance that is allowed to work on these structural members!

Define the term principal stresses.

In terms of the stress-at-a-point analysis, define what is principal stress?

what is the maximum bending stress ?

Describe the elastic strain for various types of loadings?

Please design a rapid sand filter that will effectively remove 65% of thesuspended solids in a flow of 10 cubic meters per minute. The suspendedmaterial consists of particles that are perfectly spherical with a diameter of 10microns. Please use sand with an effective size of 1 mm and a porosity of 0.5.You should limit your clean bed head loss to 0.5 meters per meter. (Pease use an attachment efficiency, α of 0.75)Viscosity of water =1.0087x10-3 Ns/m2Density of water =998.23 kg/m3What are the dimensions of this filter (Depth and Surface Area)?
