Arectangular beam of width b = 15 in., effective depth d = 20.5 in., and total depth h = 23 in. spans 18.5 ft between simple supports. it will carry a com-puted dead load of 1.08 kipsyft including self-weight, plus a service live load of 2.29 kipsyft. reinforcement consists of four evenly spaced no. 7 (no. 22) bars in one row. the clear cover on the sides is 2 in. material strengths are f y = 60,000 psi and

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg

Technician a says that in a worm gear steering system, most excessive steering free play is usually found in the gearbox. technician b says that in a rack-and-pinion steering system, excessive free play can be found in the bushings. who is correct?
