What is a metallic bond. Why metallic bonds result in well-ordered crystals. Can you please explain why can metallic bonds be conductive?
Describe three types of defects that can occur in crystal structures.
A solid shaft with a diameter of .75 in. The subject is torqued at B(35lb*ft clockwise), C(20lb*ft counterclockwise), D(40 lb*ft counter clockwise) and E(25 lb*ft clockwise).
Water, at volume flow rate Q=20 L/s, is delivered by horizontal fire hose and nozzle assembly. The hose (L = 100m, D = 75 mm, and e/D = .004) is made up of five 20 m sections joined by couplings
The composite shaft is made of a steel sleeve, which is bonded to a brass core. The outer diameters of the two parts are d1 = 40 mm for the brass core and d2 = 50 mm for the steel sleeve.
determine the correspondig angular acceleration alpha of the beam, the acceleration of C, and the distance b from B to a point P on the beam centerline which has no acceleration
If the rate of travel of the ram u is 0.5 fps, find the frictional resistance, F when 6 ft of the ram is engaged in the cylinder.
A concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
Determine the value of the strain hardening exponent for a metal that will cause the average flow stress to be 3/4 of the final flow stress after deformation.
A symmetric compound channel in overbank flow has a main channel with a bottom width of 30 m, side slopes of 1:1, and a flow depth of 3m.
Engineers propose putting flashboards on the dam to raise the water level to 10 ft. Residents a half mile upstream are worried about flooding above their present water depth of about 2.2 ft. Using Eq. (10.52) in one big half-mile step, estimate th..
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C(dot)t product of 10 (mg/L) (dot)min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
The ball at A is kicked such that theta=30 degrees. If it strikes the ground at B having coordinates x=15 ft, y= -9ft, determine the speed at which it is kicked and the speed at which it strikes the ground.
assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point. what is the time-mean speed and space-mean speed for these vehicles for this..
