Due to the difficulty of locating the precise point at which the slope of the modulus line begins to change, indicating the onset of plastic deformation and the yield point. By placing a line parallel to the modulus line it is much easier to see the precise point at which they intersect. The selection of .2% is just a convenient distance to provide a good visible intersection and assure a very reasonable degree of accuracy.

Find the yield strength from a stress-strain graph?
Follow the graph's positive slope (across the first quadrant) until the graph is no longer linear. The yield strength is determined to be the last point (with concern given to the stress value) on the linear section. After this point the graph is irregular because the material has failed to a point of no return and can no longer handle the load (stress).
What is the tensile strength of .375 bolt?
Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
What is the tensile strength of dry paper?
Tensile strength is the resilience a towel will have against being ripped. To find out the tensile strength either a machine direction or a cross direction is used. Paper is always stronger when it is pulled in the machine direction. The dry machine direction of a towel is strong will average about 32 oz./sq. in.
What is axial load?
An axial load is a force administered along the lines of an axis. This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives head first into shallow water and hits the top of his head on the bottom. This frequently causes fractures of the spine and possibly spinal cord injury. It is also commonly used to describe a specific strength of materials known as their uniaxial compressive or tensile strength and also to find the variation of their strength with increasing confining pressure (as used in triaxial testing).
Find offsets with elbows on round ductwork?
adding an elbow is like adding another piece of duct,in other words you will gain length. you have to measure using centers. lets say that you have a duct that you want to make an offset to change your location or elevation,measure the distance from starting point to finish point either end to center or center to center,say your measurement is 12in. end to center, measure the elbow from the end to the center,usually by putting it on a table or againist a wall, say your meas. is 6in. bear in mind that the elbow will fit over the duct,lets say 2in. that means the elbow will add 4in. to your duct, subtact 4in.from your 12in.meas. that leaves you with 8in. of duct to make your offset
How do you find 85.0 percent in percent yield?
if you received 85.0 percent back from your product then your percent yield is 85 percent.
What is the percent yield of 122 grams of product?
If this is the actual yield, real amount produced, then you need the theoretical yield to find the percent yield. % yield = (actual yield / theoretical yield) x 100
Why do you find percent yield?
This allows you to compare different investments. In general (other things being equal), you would normally prefer an investment which gives you a larger percent yield for any given time period.
What is the percent yield for the reaction of 6.92 g of K and 4.28 g of O2 if 7.36 g of KO2 is recovered in the laboratory?
First you need to find the theoretical yield for the reaction:2Na + O2 ---> Na2O2(1) find the theoretical yield of 3.74 g of Na, i.e. if all of the Na is reacted3.74 g Na *(1 mol Na/22.99 g Na)*(1 mol Na2O2 formed/2 mol Na reacted)*(77.98 g Na2O2/1 mol Na2O2) = 6.34 g Na2O2(2) % yield = (actual yield / theoretical yield)*(100%)% yield = (5.34 g / 6.34 g) *(100%) = 84.2% yield

Is it possible to get a percent yield over 100 percent?
Certainly. If you double your money over some period of time, you have made 100 percent. If you triple it, you have a 200% gain. Earnings are usually calculated as an annual percent gained, and it is unusual to find investments that will double in one year, but not impossible.

How do you calculate the percent yield of an element in a reaction?
The actual yield is given within the worded problem. The theoretical yield however is to be found. In order to calculate the theoretical yield, you need to convert the mass of the limiting reagent (LR) to the mass of the reagent in excess (ER). To find the limiting reagent, you need to first convert the mass of the limiting reagent to the mass of the reagent in excess (to find the theoretical yield)A. Convert mass of limiting reagent to mass reagent in excess (mass --> mass); in other words, find the mass of the reagent consumed.1. Multiply the mass of the limiting reagent by the # molecules of the reagent in excess and its molar mass.2. Divide the above by the # of molecules LR which is multiplied by its molar mass.Mass LR x # molecules ER x molar mass ER-- # molecules LR x molar mass LR3. Subtract the original mass of reagent in excess and the consumed reagent in excess.Original mass Reagent in Excess - Consumed Reagent in Excess= Reagent leftover/unused (theoretical yield).B. Find the percent yield of the product.--- Actual YieldTheoretical Yield x 100%
