A road passes through a tunnel with a semielliptical cross section 64 ft wide and 18 ft high at the center. What is the height of the tallest vehicle that can pass through the tunnel at a point 22 ft from the center? See Fig. 21.70
A saturated soil has a unit weight of 120 pcf and a water content of 32.5%. Determine the void ratio and specific gravity of the soil.
Determine the deflection of a simple uniformly loaded beam by the Ritz method,using first one term, then two terms, adn finally three terms in a sine series. Why does the coefficient of sin2piex/L vanish?
cell pressure kN/m2 100 200 300 ultimate deviator stress kN/m2 137 210 283 ultimate pore pressure kN/m2 28 86 147 determine the effective stress strength parameters
The moto draws in the cable at D with a constant acceleration of aD=8 m/s^2. If vD=0 when t=0, determine: a) the time needed for block A to rise 3 m b)the relative velocity of block A with respect to block B when this occurs.
A 200,000 cubic m highway embankment is to be constructed at dry density of 1.85 Mg/m^3 and optimum moisture content of 16% by compacting sandy silt taken from a borrow pit. The in-situ bulk density of the sandy silt is 1.92 Mg/m^3 and its average wa..
The service loads on a steel truss member are PDL: 120 kips (tension), PLL =240 Kips (tension), PWL = 200 kips (tension/compression). Steel properties are Fy = 46 ksi, Fu = 58 Ksi. Using the tables in the AISC manual, make a preliminary selection of ..
It is known that a horizontal curve starts (has PC) 90m before the vertical curve's PVC. If the superelevation of the horizontal curve is .08 and the central angle is 38 degrees what is the station of the PT
A core sample of basalt, 4 inches long and 2 inches in diameter, was tested in unconfined compression. The basalt is known to have a modulus of elasticity = 9.1 x 106 psi.
This uniformly reduces 4X10-4 cm / s to a depth of 22 meters. If the water level is about 3 feet below the surface, determine the saturated hydraulic conductivity of the layer.
If the system is released from rest in the position, determine velocity of the ball (a) when it has dropped a vertical distance of 10 inches and (b) when the rod has rotated 35 degrees
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
A simply supported beam (one end has a pin support and the other a roller support) is 10 ft long. The width of the beam is 3.5 in. The beam supports three concentrated loads
