You are provided with a brittle material whose ultimate tensile strength is 25% of its ultimate compressive strength. Plot the failure loci for each of the brittle failure criteria. For example, you may want to to either
(a) Create a 2D contour plot in terms of o1 and o3 (sigma 1 and 3) axes,
(b) Identify the shear strength of the material on thes axes. Use your own creative method for conveying your solution.
HINT: use Match CAD or Matlab.
Fixed GPS broadcast stations enable users to make differential measurements to other points whose positions are needed. In the US, there are two such networks two such networks of broadcast stations, name one (blank)
Write a script file to simulate 100 plays of a game in which you flip two coins. You win the game if you get to heads, loose if you get two tails, and flip again if you get one head and one tail.
A permanent endowment at the University of Alabama is to award scholarships to engineering students. The awards are to be made beginning 5 years after the $10 million lump-sum donation is made.
The density of 70.5 wt% aqueous perchloric acid is 1.67 g/mL. a. How many grams of solution are in 1.000 L? b. How many grams of HClO4 are in 1.000 L? c. How many moles of HClO4 are in 1.000 L?
An inspector is paid $10/hr and can sort 10 rings/min. Assume that a new method allows her to sort 20 rings/min but costs $500 to implement. Is it worth implementing the new method for a batch of 50,000 rings? At what point does the new method pay of..
A feed containing 15% by weight of solids is to be concentrated to 40 % solids using a double effect backward feed evaporator. The first effect is heated by steam at 413 K.
If = 300 N , determine the required minimum compression in the spring so that the wedge will not move to the right. Neglect the weight of A and B. The coefficient of static friction for all contacting surfaces is .2 Neglect friction at the rollers.
what would be better a truss with all 60 angles or a truss with a 30 60 90 angle for a bridge design what would be the best design
If the normal stress is 2,500 psi, Poisson's ratio is 0.25 and Young's modulus is 10,000 ksi, calculate the normal strain.
a cantilever beam is additionally supported using two tierods. Both rods attach to the end of the beam. One rodcomes off at 45 degrees and attaches to the same wall that the beamis solidly fixed to
A proposed combined cycle power plant is shown below. A gas turbine engine, the topping cycle, takes air at state 1 (T=300 K, P=100 kPa) and compress it irreversibly (hc=0.87) to state 2.
Stormwater controls are typically designed by civil engineers. Stormwater is collected in pipes below the ground and routed to nearby surface water.
