Energy per unit length of dislocation is Gb2/2. Dislocations dilates a closed packed crystal structure veryslightly, since at their cores the atoms are not close packed:dilation is b2/4 per unit length of dislocation. It is found that the density of a bar of copper changes from 8.9323Mg m-3 to 8.9321 Mg m-3. when it isvery heavily deformed. Calc (a) dislocation densityintroduced into the copper by the deformation and (b) the energyassociated with the density. Compare the results with the latentheat of melting of copper (1833MJ m-3) (b for copper is 0.256nm, Gis 3/8 E).
Figure out the times he was at each of these companies, who else was there at the time and how they might have collaborated. Include the technologies that were in use or being developed.
Assume that (t) is givenin degrees, and write the matlab statement to evaluate tan (t) aslong as the magnitude of cos(t) is greater then or equal to(10^-20). If the magnitude of cos(t) less then (10^-10,
A thermal reservoir (T=308K) is brought in contact with the tank, transferring enough heat to the tank to raise the pressure inside to 4 bar. Calculate the entropy changes of the refrigerant and the thermal reservoir
determine the elastic elongation that would be expected for a 16-mm-diameter rod of the same material if the rod were 1.6 m long and subjected to a tension force of 3.3 kN.
The tank has an inside diamater of 100 cm and will be subjected to a maximum internal pressure of 820 kPa. The allowable tensile stress in the wall is 83 MPa, and the allowable tensile stress in the weld is 55 MPa.
A log that is 2 ft in diameter is to be cut into a rectangular section for use as a simply supported beam. The material is wood select structural grade (Douglas Fir) with a specific gravity of 0.017 lb/in3.
A pipe is to be installed under the ground on a bed of aggregate 6 in. thick. The entire weight on the aggregate from pipe and soil above the pipe is 1800 lbs. per linear foot of pipe. What is the pressure on the soil if theta is 45 degrees
Two materials (wrought iron, ks = 0.046 mm, and galvanized iron, ks = 0.15 mm) are being considered for a new pipeline. The expected discharge is 0.15 m3/s. Both the head loss and cost are sought for.
Knowing that each member has a 2 3 4-in. rectangular cross section and that each pin has a 12 -in. diameter, determine the maximum value of the average normal stress (a) in member BE, (b) in member CF.
Plot the stress-strain curve and determine the proportional limit, modulus of elasticity (i.e., the slope of the initial part of the stress-strain curve), and yield stress at 0.2% offset. Is the material ductile or brittle
A loose uniform sand with rounded grains has effective grain size of 0.05 cm. What will be the Coefficient of permeablity of sand
1. a rectangular channel 5 m wide carries a discharge of 10 m3s at a uniform depth of 3 m. the channel is running on a
