Determine a set of a rectangular beam design values b,d and As that will be needed to support a factored bending moment Mu= 450 Kip-ft.Use f'c= 4500 psi and fy= 40000 psi. Use beam width of approximately 0.6 times the effective depth.( b=0.6 d).
A rear-wheel-drive 3000lb drag race car has a 200-inch wheel base and a center of gravity 20 inches above the pavement and 140 inches behind the front axle. The owners wish to achieve an initial acceleration from rest of 15 ft/s on a level paved s..
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
Water flowing in a wide channel of depth 35 cm undergoes hydraulic jump that resulted in energy dissipation of 72%. Estimate (a) the downstream depth, (b) the volume flow rate per meter of width.
Wastewater enters and anerobic pond at a BOD of 246 mg/L and a flowrate of 0.1 m^3/s. The waste degrades at a rate of 0.40d. Effluent from the lagoon must have a BOD of 23.9mg/L.
Determine the horizontal reaction that is developed on the gate at C.
Assume that you are going to buy a car work $25,000. You will be able to make a down payment of $3,000. The remaining #22,000 will be financed by the dealer. The dealer computes your monthly payment to be $547.47 for 28 months of financing.
determine by trigonometry (a) the required tensoin T2 in the left hand portion if the R of the force exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R.
Assuming the center of gravity of the student aligns with the axis of the pole and the pole has an elastic behabior, how high can they climb (in meters, m) just before the pole buckles
A sample of natural glacial till was taken from below the groundwater table. The water content was found to be 52%. Estimate the wet density,dry density,buoyant density,porosity,and void ratio. Clearly state any necessary assumptions.
The man has a mass of 65kg and stands motionless at the end of the diving board. If the board has the cross section, determine the maximum normal strain developed in the board. The modulus of elasticity for the material is E = 117GPa
A 2.50-g sample of a large biomolecule was dissolved in 13.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
A Carnot power cycle uses 0.45 kg air, modeled as an ideal gas, as the working fluid. The net work, Wcyc, is 93.64 kJ and the thermal efficiency is 0.6. During the isothermal expansion the volume triples.
