1.(a) Derive Linear density expressions for FCC [100] and [111]directions in terms of the atomic radius R.
(b) Compute and compare linear density values for these same twoplanes for copper.
2.Calculate the radius of a palladium atom, given that Pd has an FCCcrystal structure, a density of 12.0 g/cm^3 , and an atomic weightof 106.4 g/mol.
knowing that the coefficient of static friction between the collar and the rod is .35, determine the range of values of p for which equilibrium is maintained when 0=50deg and M=20Nm
A disk spins within an oil-filled enclosure, having 2.4 mm clearance from flat surfaces each side of the disk. The disk surface extends from radius 12 to 86 mm.
Discuss the differences between how engineers see themselves and how the public sees engineers
A train starts from rest at station A and accelerates at 0.5m/s^2 for 60s. Afterwards it travels with a constant velocity for 25min. It then decelerates at 1 m/s^2 until it is brought to rest at station B.
Establish a grass cover over a 10ha landfill. The root zone of the grass is 40cm deep. Increase the volumetric water content of root zone from 12% to 24%. How many cubic meters of water are needed?
As part of the procurement or contracting department of this federal agency, you need to demonstrate your understanding of the different project delivery methods and contract types available to the agency.
An existing power plant has been found to produce SO2 concentration of 20µg/m3 at a distance of 800m directly downwind from the stack when the wind is 4m/s from the north during a class C stability situation.
A stack (T=550*F and P=750mm Hg) was sampled using EPA Method 5. The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T=60*F and P=800mm Hg). The mass of particles collected was 1.50g.
If the free surface at a distance from the axis of the vortex, which is sufficient for its effect to be negligible, is 180 mm above datum, what will be the height above datum of a point B on the free surface at a radius of 100 mm
Evaluate the pressure head at point a and determine the vertical effective stress at point b and evaluate the lateral pressurein the brown clay
Compare bar charts and precedence diagrams in terms of the ease with which activities can be added to the schedule.
The object ABC consists of two slender rods welded together at point B. Rod AB has a mass of 1 kg and bar BC has a mass of 2 kg. Knowing the magnitude of the angular velocity of ABC is 10 rad/s when thetha is zero.
