The beam shown is supported on pedestals 20-in. wide. The loads are service loads, and the distributed load includes the beam weight. The clear span is 24′-4″. Use f′c = 4000 psi; the reinforcing steel is A615 Grade 60. Design shear reinforcing for the beam:
a. Between the point load and the left reactionb. Between the point load and the right reaction

two boxes made of the same material have the same masses but their dimensions are different. the bases of the boxes in
A cylindrical specimen of a metal alloy 51.3 mm long and 11.1 mm in diameter is stressed in tension. A true stress of 350 MPa causes the specimen to plastically elongate to a length of 57.9 mm. If it is known that the strain-hardening exponent for th..
Determine the resulting stress equations for σx, σy and τxy given the Airy's stress function ? = a1x^4 + a2(x^3)y + a3(x^2)(y^2) + a4x(y^3) + a5(y^4), where ai are constants. Also determine, if any, the restrictions between constants.
for a neutral surface layer, plot wind speed against height on linear and on semi-log graphs for friction velocity of .5 m/sec and aerodynamic roughness length.
Find the diameter of a pipe to convey the superheated steam flowing into the mixing process if the speed of the steam is 20m/s and also ascertain the condition of the resulting mixture.
A gaseous mixture with a molar analysis of 20% CO2, 40% CO, and 40% O2 enters a heat exchanger and is heated at constant pressure. An equilibrium mixture of CO2, CO, and O2 exits at 3000 K, 1.5 bar. Determine the molar analysis of the exiting mixt..
