An underground storage vault is to be constructed to serve as a detention pond for a heavily urbanized area. The walls of the vault will be vertical, but the flow will be sloped along its length to
Diameter of the hose and the nozzle are .25ft and .1ft respectively. If the pressure inside the hose is 60 psig and the flowrate is 1.2 ft^3/s, calculate the horizontal force required to hold the ho
A rectangular beam 4 inches wide and 12 inches height must sustain a maximum bending stress of 12,500 Lbs/in^2. A) Sketch beam and show neutral axis. B) Solve for the maximum bending moment.
A brass cube (E=100 GPa, v = 0.25(Poisson's ratio)) is 100 mm long per side. A compressive force of 100kN is applied to one side, while a tension force of 200 kN is applied to a second side.
The sodium cyanide solution ([NaCN]-total = 0.01 M) is kept at pH 10.4. The pH is kept high to keep the cyanide in the CN- form. If CN protonates by the reverse of the HCN dissociation reaction,
