Is tensile strength of cold rolled steel is greater than yield stress?
For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.
What is the unit for yield strength?
kg/cm² Yield strength is same as yield stress and are in dimensions of [force]/[area] In US, typical unit would be PSI ( lb/in^2) or KSI (kilo lb/in^2) In SI, typical unit would be Pa ( N/m^2) or MPa ( million N / m^2)
Is Modulus of rupture the same as Maximum stress?
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
What do you mean by bolt uniform strength?
Bolt of uniform Strength means that the entire length of the bolt is subjected to same intensity of stress,that is stress in the shank portion and the threaded portion are same.this is achieved by reducing the diameter of the shank to core diameter of the thread.

Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
How would you describe a metal that has a yield strength and tensile strength that are the same?
Brittle

What happens if the yield stress and tensile stress of a steel bar is alomost the same?
Yield strength is the stress at which a material deforms plastically- basically, when you take the load off, it won't go back to the same dimensions it started at. Tensile strength is the stress at which the material breaks. In materials where the yield and tensile strengths are close numerically, like glass, there is a very small plastic range. These materials are thought of as brittle. In materials where the yield and tensile strengths are far apart numerically, like soft aluminum, there is a very large plastic range. One potential upside of a larger plastic range is that brittle failures are often catastrophic. A material with a larger plastic range can allow a part to be designed that will fail in overload by deforming until the part is unusable, rather than fracturing completely.
What is stronger 7075 aluminum or 4130 chromoly?
Chromoly is stronger in terms of tensile strength and both metals are about the same in yield or bending strength.
What are the Advantages and disadvantages of working stress design and ultimate strength design?
Ultimate strength design assumes the entire cross section of a member is subjected to its yield stress and will generally save material, but be less conservative given the same factor of safety.
What is difference between von mises and principle stress?
Whenever an elastic body subjected to loads in its 3 dimensions, the stresses will get developed along the principal axis of the body. These are the principal stresses. These stress should not exceed the yield stress of the material. Von Mises (1913) postulated that, even though none of the principal stresses exceeds the yield stress of the material, it is possible for yielding of the same from the combination of stresses. The Von Mises criterion is a formula (refer any textbook which content failure theories for Ductile Materials) for combining these 3 stresses into an equivalent stress, which is then compared to the yield stress of the material.

What is the yield strength of polycarbonate plastic?
The yield stress of any plastic is usually not use to describe the material because all plastics yielding stress is a function of the rate at which it is loaded and its temperature. For example if you leave something like silly putty on the corner of a table it will eventually creep over the edge of the table under its own weight, but if you cool it down to can use it to hit nails into wood. Same thing applies to poly-carbonate and other plastics just to a lesser extent. Often the ultimate stress is used to determine if a plastic will fail but even that assumes that the plastic is a room temperature.
