Segment A of the composite beam is made from 2014-T6 aluminum alloy and segment B is A-36 steel. If w = 0.9 kip/ft, determine the absolute maximum bending stress developed in the aluminum and steel. Sketch the stress distribution on the cross section.
Determine the tension T in the cable and the magnitude of the pin reaction at O
A crate has a weight of 50 lb and is acted upon by a force having a variable magnitude of P=20t, where p is in pound and t is in seconds. compute the crates velocity two seconds after P has been applied. The crates initial velocity is 3 ft/s down the..
A cylindrical soil sample fails under an axial vertical stress of 160 kN/m^2, when it is laterally unconfined. The failure plane makes an angle of 50 degrees with the horizontal.
The subcritical water level in the channel downstream from the stilling basin is at an elevation of 100 feet above the datum. assume no energy loss over the spillway, determine the invert of the stilling basin required to form a hydraulic jump in ..
Two identical complete-mix activated sludge units are connected in series; one-half of the sludge recycle flow rate, QR, is recycled to the primary effluent pipeline which handles a flow rate Q, and the other half is recycled to the effluent line fro..
