1.It is desired to produce an iron-carbon allow that has a minimum hardness of 200 HB and a minimum ductility of 35% RA. Is such an ally possible? If so what its composition and microstructure? If this is not possible explain why
2.Consider a steel containing 0.6% carbon and 10% chromium. Estimate the eutectoid temperature and concentration. What is the proeutectoid phase?
3.A man bought a 5% tax-free municipal bond .It cost $1000 and will pay $50 interest each year for 20 years.At maturity the bond returns the original $1000 .If there is 2% annual inflation ,what real rate of return will the investor receive?
4.You may pay $15,000 for an annuity that pays $2500 per year for the next 10 years . You want a real rate of return of 5% , and you estimated inflation will average 6% per year. Should you buy the annuity?
determine the total dead load, per foot of length, each beam must support.
Assume frictionless flow in a long, horizontal, conical pipe. The diameter is 12 inches at one end and 6 inches at the other. The pressure head at the smaller end is 16 feet of water.
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much
An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. For this water main calculate the head loss
A cylindrical chimney,1 m in diameter and 2.5 m tall is exosed to a uniform 50km/hr wind at standard atmospheric conditions.End effects and gusts may be neglected.
Fluid flows steadily, at a volume rate Q, through a large pipe and then divides into two small pipes, the larger of which has an inside diameter of 25 mm and carries three times the flow of the smaller pipe.
vehicle A enters the interstate and travel at 60 mph for 1/2 hour, stops for 30 mins then continues at 70 mph. If a vehicle B enters the interstate at the same location as A,
The 90lb door has its center of gravity at G. A)Determine the components of reaction at hinge A if hinge B resists only forces in the x and y directions and A resists forces in the x,y,z directions.
Define what each term in the equation means. Overall, what quantity is being conserved? Under what conditions might you be justified in assuming that non-linear terms are not important
SAMPLE B:has size 10,mean 20 and variance 36 .calculate pooled sample variance
