1.Consider a diver weighing 200 lb at the end of a diving board that cantilevers out over 3 ft. The diver oscillates at a frequency of 2 Hz. What is the flexural rigidity EI of the diving board?
2.Given a 22.414 liter volume of air at STP containg: 21.224kPa oxygen, 79.119 kPa nitrrogen, 0.946kPa argon,and 0.036 k carbondioxide. Find the gram molecular weight of the air.
a railway wagon weighing 40 kn and moving with a speed of 8 kmh is stopped by a buffer of 4 springs whose allowable
At Point A, in a pipeline carrying water (γ=62.4 lb/ft^3) the diameter is 4.0 ft, the pressure is 10 psi, and the velocity 4 ft/s. At point B, 6ft higher than point A, the diameter is 2 ft and the pressure is 2ps
Assume that there is only one phase present and that the formation is homogeneous, but anisotropic. Further, assume that viscosity, formation volume factor, and the areas available for flow are constant spatially. Last, assume 3-D flow using x, y,..
It is commonly known that there are 16 ounces in 1 lb. Consider a 0.5lbf glass that weighs 1 lbf when filled with 8 ounces of liquid. Determine the liquid density in British gravitational units and in SI units.
a vertical curve is to connect two tangents that intersect at station 5000 and the elevation 500.00ft. the back tangent
The force of the expanding gases on a 0.02 kg bullet is given by f=f0-f.1*t . Initially stationary at x=0 , the bullet reaches a speed of 1000 kph by the time it exits the gun. f0 = 7000 N and f1=2.9*106 N/s.
A differential leveling loop began and closed on BM bridge (elevation 103.895m). The plus sight and minus sight distances were kept approximately equal
Assume for your calculations that each member is in tension, and include in your response the sign of each force that you obtain by applying this assumption.
Assuming the resulting hole acts like an isentropic converging nozzle with a throat diameter of 0.08 cm, calculate the mass flowrate in kg/s of methane that initially escapes from the tank.
1.what would the bc ratio be if the light poles were twice as far apart as assumed above?2. what is the ratio of night
Define the meaningof C•t product. In addition to Cand t, what factors influence the rate of chemical disinfection? What kind of microorganism is most readily inactivated byfree chlorine? What kind is most difficultto inactivate?
The 30-Mg freight car A and 15-Mg freight car B are moving toward each other with the velocities VA= 20 km/h to the right and VB= 10 km/h to the left. the spring constant on car A is k= 3MN/m.
