For an intermediate beam in 3 bays by 3 bays (each bay is 20' by 20') floor plan, draw the envelope shear and moment diagrams taking into account effect of pattern loading. show values of maximum shear and moments. Assume pin supports at the beam ends. DL=150 psf. LL=100 psf. ignore self weight of beams.
assume lateral support at each support and every 20 ft between supports. assume constant depth for girder. use A 572 grade 50steel. use LRFD methods. minimum web thickness is 5/16 inches.
If the normal stress is 2,500 psi, Poisson's ratio is 0.25 and Young's modulus is 10,000 ksi, calculate the normal strain.
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
A discharge from a power plant cooling tower has a temperature of 81 degrees C and flows into the stream at a rate of 3 cubic meters per minute. What is the temperature in the stream downstream of the cooling tower discharge
A typical propane tank that we use for barbeque initially contains a pressure of 10 psi. The pressure is low, so we take it to the local store to fill the tank with more propane. After filling,the pressure is 100 psi.
Over the past 3 years, there have been 14, 13, and 15 crashes on this section of College Street. The two-way ADT on this section is 16,474 vehicles per day. What is the annual crash rate for this section of College Street
The "supersoaker" water gun can shoot more than 30 ft in the horizontal direction. Estimate the minimum pressure, , needed in the chamber in order to accomplish this. List all assumptions and show all calculations.
Use the bisection method to find the root of the equation f(x) = x 2 - 4sin(x) = 0. For initial bracketing interval [a,b] , take a=1 and b = 3.
What is the settling velocity of a .5 micrometer silica sphere at 20 degrees Celsius and an ambient pressure of 150 kPa. The density of silica is 2600 kg/cubic meter.
The distance covered by an aerial photograph is determined by both the focal length of the camera and the tilt of the camera. Although the tilt is usually small, both archaeological and Canadian photographs often use larger tilts.
