An axial load P is supported by a short W8 X 40 column of a cross-sectional area A = 11.7 in2 (inches squared) and is distributed to a concrete foundation by a square plate as shown (in the attachment) Knowing that the average normal stress in the column must not exceed 35 ksi and that the bearing stress on the concrete foundation must not exceed 3.5 ksi, determine the side a of the plate that will provide the most economical and safe design.
couplings , each with a loss coefficient of k=0.15, are located every 10 m along thehose. the nozzle outlet diamter is d= 25 mm, its minor losscoefficient is k=0.02 based on outlet velocity
The central angle is 35 degrees, the superelevation is 0.08, and 20.6 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
An engineer is considering the development of a small wind turbine(D=1.25m) for home applications.The design wind speed is 15mph at T=10 degree celsus and p=0.9 bar.The efficiency of the turbine is n=20%,meaning that 20% of the kinetic energy in the ..
