a point within an elastic body was subjected to a system of plane stress. strain gauges were used to measure that would allow for the calculation of principal strain and stress values at that point.with the given information:
the direct strain at an angle of 30o,to one of theprincipal axes was 1.34x10-3 and the corresponding shearstrain was 8.52x10-4. Calculate as many principal ormaximum strains at the point
A quality of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor.
What is work? Why is it path dependant? Derive the expression for reversible work from a closed system containing a simple compressible substance.
The tank contains water to depth of 2m and oil (SG=0.8) on top of the water to a depth of 1m. Determine the magnitude and location of the resultant force acting on one end of the tank (i.e. 3m high by 3m wide).
Suppose that a water treatment plant has a Parshall Flume with a 4 ft wide throat. a) If the upstream depth of the water (ha) is 1 ft and the depth of the water in the throat section (hb) is 0.65 ft, what is the flow rate in gpm
Calculate soil moisture using daily (or any other scale) precipitation and temperature . Use the Richard's Equation and Darcy's law (Or any theory you like attached to soil moisture content determination ).
Select the best rectangular HSS for a column to support a service dead load of 30 kips and a service live load of 90 kips. The member is 22 feet long and is pinned at the ends.
A tangent section of highway has a -1.0% grade and ends at station 4+75 and elevation 82 ft. It must be connected to another section of highway that has a -1% grade and that begins at station 44+12 and elevation 131.2 ft.
The driver of the vehicle does not look for oncoming traffic. Road conditions and vehicle speeds on the highway are such that it takes 1.5 seconds for an oncoming vehicle to stop once breaks are applied.
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 spherical drop of water has r = .1mm . If the surface tension of water is 72 dynes/cm, calculate the pressure difference across the interface.
A proposed square footing carrying a total load of 500 kips is to be constructed on a uniform thick deposit of dense cohesionless soil. The soil's unit weight is 135 pcf, and its angle of internal friction is 38 degrees.
A 10 inch steel pipeline 100 feet long carriers 2000 gpm of crude oil. Calculate the head loss when the oil is at a) 80 degree F b) 110 degree F.
