The maximum wind pressure on the traffic sign is 200 kg/m2. The maximum allowable shear stress is 350 kg/cm2. Design the traffic pole (only vertical element) against torsion knowing that angle of twist at the base should not exceed 6°. A steel pipe with thickness of 3mm will be used in building of the traffic pole.
The segment of river shown has a rectangular cross-section, with width 50 ft. The river bed is at angle theta=10 degrees from horizontal. The average velocity is 2 ft/s at the upstream end, and 3 ft/s at the downstream end.
A coal fired power plant can be modeled as a heat engine. If the power output of the plant is 200 MW and the thermal efficiency is 42%, determine the amount of coal used per day if the heat of combustion from the coal is 24,000 kJ/kg.
The ultimate normal strength of the wood is ?ult = 1800 psi and the ultimate shear strength of the wood is fault = 800 psi. The width of the specimen under tension is b = 1.7 in, and the specimen is 1.0 in thick.
Design a one way slab to support a uniform live load of 300 psf. The beam is simply supported with a span of 20 ft. Use a reinforcement ration ( Ps) of 0.008 Use f'c=3000 psi and fy=60000 psi.
Determine the horizontal distance, given:Stadia Top=8.5 ,Stadia Bottom 6.21, vertical angle= -8 degrees 42 minutes.
A triaxial test was performed on a dry, cohesionless soil under confining pressure of 144 kN/m^2. If the sample failed when the deviator stress reached 395.8 kN/m^2, determine the soil's angle of internal friction.
The temperature in the stack is 300 F and the pressure is 725 mm Hg. If the total flow rate of gas out of the stack is 190 standard cubic meters per second, calculate the total mass emissions of particulates out of the stack in kg/day.
A study of the traffic using a tunnel showed that the following speed-concentration relationship applies. Find the capacity of the tunnel, the values of speed and oncentration at capacity, and the jam concentration.
A 4-m-long steel rod must not stretch more than 3 mm and the normal stress must not exceed 150 MPa when the rod is subjected to a 10- KN axial load.

A multinational engineering consulting firm that wants to provide resort accommodations to certain clients is considering the purchase of a three-bedroom lodge in upper Montana that will cost $250,000. The property in that area is rapidly appreciatin..
A two stage rocket with a total mass of 925kg is traveling at a speed of 6.6 10^3 m/s away from the earth . A predesigned explosion separates into two sections of equal mass that move with a speed of 2800m/s relative to each other along the original ..
