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. Calculate by what factor the mass of propane has increased inside the tank? (Assume the temperature and volume are constant before and after filling the tank.)
A gas occupise 250 ml and it's pressure is 550mm Hg @ 254C how many moles of gas are in this sample? (convert mm Hg to atm).
Groundwater moves through a sandstone porous media and is driven by a gradient of -0.05 directed at an angle of 60 degree counterclockwise from the x-axis.
A direct shear test is performed on a saturated specimen of loose sand. A normal stress equal to 100 kPa is applied and a maximum shear stress of 75 kPa is measured in the shear test. Determine the principal stresses and the orientation of these p..
A proposed earthen dam will contain 5,000,000 cubic meters of earth. Soil to be taken from a borrow pit will be compacted to a void ratio of 0.78. The void ratio of soil in the borrow pit is 1.12. Estimate the volume of soil (cubic meters) that mu..
An overpass is being built over the PVI of an existing equal tangent sag curve. The sag curve has a 70 mi/h design speed, and G1 = -6%, G2 = +3%.
Given: elastic modulus of steel is 200 GPa, yield and ultimate tensile strength of steel are 600 and 750 MPa, respectively.
A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest. ... forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.
After falling from rest from a height of 32 m, a 0.45 kg ball rebounds upward, reaching a height of 22 m. If the contact between ball and ground lasted 1.5 ms, what average force was exerted on the ball?
Compute the maximum acceptable service load on an A36 steel plate tension member 1/4in.x12in. having a single line of holes parallel to the direction of loading. The load is 25% dead load and 75% live load, and 7/8in. diameter bolts are used.
What are 3 of the equivalent fixed-point problems for f(x) = x2 - x -2=0?
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate).
A fully loaded, ocean going container ship is just stable about its longitudinal axis (roll). The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the ..
