An infinite amount... for any given Strain, there is a corresponding Stress value. To see what I mean, plot a Stress Strain graph in excel using 10 sets of values, then do another using 20... the one with 20 has a smoother curve, see where I'm coming from?

What is shear strength of T6061?
Depends on what alloy you mean. If you are talking about pure Al (AISI1xxx), it is generally accepted to yield about 7-11Mpa. Another thing to consider is that Al does not have as pronounced yield as say Fe systems. The 0.2% offset stress is used in most calculations regarding Al yield stress and is calculated as follows: L = length of sample ->0.2%*L=0.2% offset strain. Plot this point on stress/strain graph and draw line from this point on the strain axis parallel to the elastic slope of the material until it reaches the data points. This intersection is the 0.2% offset stress point.
What is the formula for shear and stress?
Just like axial stress, shear stress is force divided by area. The area is the surface the force acts over. For example, imagine two wood blocks that are nailed together. If you apply a force to the top block orthogonal to the longitudinal axis of the nail and the same force in the opposite direction to the bottom block, the shear stress (𝝉) in the nail is 𝝉 = F/A or F/(πr2) where r is the radius of the nail.
Why null values in database?
The 'null'-content of any given field is just that. It's a 'nothing'. Example, if you create a database to hold chemical values for instance. If the values are, for example, real nubers. That would imply that any value that has 0 in it, is just that; zero. It was beeing measured, and found to contain zero. On the other hand if a value was not tested, the value of that compound should be set to 'null'. If a 'null' value isn't supported by the database a workaround is to set 'null' values to -1 (as per the example above). --
Disadvantages of enumeration in c?
The big disadvantage I've found is that you might mistake it for a user-defined type. It's not; you still have to use int for your variable type and compilers will not do anything to help restricted assignment to values from the enumeration.
Why all the oscillations found in nature mechanical electrical etc are sinusoids?
The sine wave is the curve that naturally occurs when the restoring force is proportional to the displacement. The math is a little complicated (the sine wave in this case is the solution of the corresponding differential equation), but the point is, this relationship between the force and the displacement is a fairly common situation.
What information might you get from stress-strain curve?
As a simple answer, from this curve the mechanical properties of the material can be found such as: Elasticity Modulus (E) which is the proportion of Stress to the Strain, the higher value means under a fixed value pressure the material oppose more to deflect. Reversely, the lower value shows that the material is more flexible. Other information such as Yield Strength, Ultimate Tensile Strength and also from the area below this curve the material toughness can be obtained.
What is proof Stress for Steel?
proof stress can be found by referring to the stress/strain curve at the point where strain is = 0.2% original volume (the material has grown 0.2% in volume) proof stress will be given as a measurement of energy (MPa,KPa etc.) as it specifically refers to the amount of energy required to stress the material to 0.2% its original volume.
How do you derive the supply curve of an industry from the supply curve of the firm?
Set MC=AVC and solve for the values that a firm will produce at. Once you've found these values, set price = MC(S(p)) and solve for supply in terms of quantity.
What are some criticisms of the general strain theory?
tests on gst have been found to have moderate to strong empircal support. The theory really isn't about strain, it's about stress. stole findings from other theories. Use of control, slt variables to explain coping.
What are the injuries found in a muscle strain?
A strain is a torn or stretched muscle or tendon.
What makes the range less desirable than the standard deviation as a measure of dispersion?
Range can include outliers that are not normal values and can skew overall data. Most relevant values can be found within one or two standard deviations on a normal curve.
What role does density play in nature?
Density is important in nature as it affects the distribution of living organisms and resources. Higher density can lead to increased competition for resources such as food and space, while lower density can allow for more space and resources for individuals. Density can also impact the functioning and stability of ecosystems, influencing factors like predation, disease transmission, and population dynamics.
What happened when griffith the mice with the harmless R strain bacteria alone?
t He then took the R strain (rough strain) and injected it into the mice and found that they did not contract the pneumonia illness and survived the insertion of the strain
What is a battleship curve?
A battleship curve is a region found in archaeology where it is thought a battleship may once have lain.
What is a battleship-shaped curve?
A battleship-shaped curve is a region found in archaeology where it is thought a battleship may once have lain.
