1.The composite bar consists of a 20mm diameter A-36 steel segment AB (Es=200GPa) and 50mm diameter red brass C83400 (Eb=101GPa) end segments DA and CB. Determine the displacement of A with respect to B due to the applied load.
2.The tapered member is fixed connected at its ends A and B and is subjected to a load P = 7 kip at x =30in. Determine the reactions at the supports. The material is 2in. thick and is made from 2014-T6 aluminum (Eal = 10,600ksi).
Consider a state with a total water withdrawal of 4.5 bgd in 2000. This was distributed as follows: municipal use 1.0 bgd, industrial use 1.5 bgd, and steam electric cooling 2.0 bgd. Assume a 2000 Population of 10 million and a projection of 12 mi..
The tower crane is used to hoist the 2-Mg load upward at constant velocity. The 1.5-Mg jib BD , 0.5-Mg jib BC , and 6-Mg counterweight C have centers of mass at G1 , G2 , and G3 , respectively.

For a three span continuous beam ( three 20' spans ), subjected to some uniform load, what is Cb for each span. Assumed the beam is braced against translation and rotation at each support.
A young engineer is asked to design a thermal protection barrierfor a sensitive electronic device that might be exposed toirradiation from a high-powered infared laser.
A 100 ft cut steel tape was used to measure between two property markers. The rear surveyor held 93 ft, while the head surveyor cut .67ft. What was the distance between the markers
Cyanide solutions used for heap leaching are made up of sodium cyanide (NaCN). The sodium cyanide solution ([NaCN]-total = 0.01 M) is kept at pH 10.4. The pH is kept high to keep the cyanide in the CN- form.
The temperature in the stack is 350 degrees F and the pressure is 725 mm Hg. If the total flow rate of gas out of the stack is 200 standard cubic meters per second, calculate the total mass emissions of particulates out of the stack in kg/day.
Using the data available in Appendix B, determine the slope of the line when the plate is subjected to a 45-kip centric axial load.
