For the beam shown, make the following computations:
a) determine the stresses in the steel and concrete under the service loadsb) compute the immediate deflection produced by the total loadc) estimate the additional long-term deflection if the live load acts continuously
use f'_c = 4 kips/in^2, and f_y = 50 kips/in^2
A container of volume 0.04 m3 contains a mixture of saturated water and saturated steam at a temperature of 250oC. The mass of the liquid present is 9 kg. Find the total mass, quality of steam, specific volume, specific enthalpy, and specific inte..
The base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque. If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for.
Consider two alternative water resource projects, A and B. Project A will cost $2,533,000 and will return $1,000,000 at the end of 5 years and $4,000,000 at the end of 10 years.
Is the system within membrane manufacturer's warranty requirement of maximum flux rate of 14 gfd? What is the annual power cost of the RO system?
Four pumps are to be used in 0.5-m diameter wells at the four corners of the site. Determine the required pumping rate. The aquifer has T = 1600 m^2/day and the wells each have a radius of influence of 600 m.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
A constant head permeability test was conducted on a clean sand sample. The diameter and length of the test specimen were 10 cm and 12 cm respectively.
At a section in a beam the tensile stress due to bending is 70 N/mm 2 and there is a shear stress of 25 N/mm 2 . Determine from first principles, the magnitude and direction of the principal stresses and calculate the max shear stress.
The forces F1, F2, and F3, all of which act on point A of the bracket, arespecified in three different ways. Determine the x and y scalar components of each of the three forces.
