A rectangular concrete beam of width b = 24 inches is limited by architectual considerations to a maximum total depth of h = 16 inches. it must carry a total factored load moment of Mu = 400 ft-kips. Design the flexural reinforcement for this member, using compression steel if necessary. Allow 3 inches to center of the bars from the compression or tension face of the beam. Materal strengths are Fy = 60,000 psi and F'c = 4,00 psi. Select Reinforcement to provide the needed areas , and show a sketch of yuor final design, including provision for no.4 stirrups.
You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
hydrogen is flowing in a 50 mm diameter pipe at a mass rate of 0.01 kg/s. at section 1 the pressure is 280 kPa abs and t= 25 . what is the average velocity?
A Silane contains 90.31 % silicon and 9.69 % hydrogen by mass. The compound has a molar mass of 62 g/mol. Determine the compound's empirical and molecular formula.
A hollow circular, gray cast-iron pipe supports a red brass rod and weight W = 2 kips, as shown. The outside diameter of the pipe is d = 6". If the allowable compressive stress in the pipe is 5000 psi and the allowable shortening of the pipe is 0...
If e is some value at midspan and e=0 at each end of the beam, and the cable within the beam has a parabolic profile. what is the expression I need to use to determine e at some other lenth along the beam
The four approach volumes per day at this intersection are 28,648, 23,856, 12,150, and 10,174. The crash totals for the last 3 years are 91, 96, and 87. What is the annual crash rate for this intersection

Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
Susan's 12.0 baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30 degrees above the floor. The tension is a constant 31.0 and the coefficient of friction is 0.210. Use work and energy to find Paul's ..
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
