Elastic limit Definition and 13 Threads

Point B is elastic limit and point C is yield point. From this link: https://en.m.wikipedia.org/wiki/Yield_(engineering)#Definition The definition given is: Both seems to refer to same definition, it is the point where the elastic deformation ends and plastic deformation begins. But from...

What I do not get is why should a stress much lower than yield point cause deformation in a material? If temperature is high intermolecular attraction is reduced and thus even low stress can deform things. But if it is low Then a force lower than yield point should be less than intermolecular...

Hi All I am trying to understand a stress / strain curve for a ductile material. But I am struggling with understanding the difference between the Elastic Limit and the Yield Point. I define these terms as:- Elastic Limit - Is the point on the stress/strain curve where the material will...

I don't understand the difference between the elastic limit and the yield point. I understand that if you stretch a material within the elastic limit, then the material should return to its normal shape. However, the yield point is described as the point at which a permanent increase in length...

This is probably simple for an engineer, but I’m a zoologist and analytical chemist and so I would rather ask those who know. I have camera traps out on the African bush, that are monitoring the responses of leopards to artificial scents. The cameras are in steel boxes to protect them from...

Homework Statement A platform (m = 5,0kg) is suspended from 4 steel cables whose length is 3,0m and diameter 2mm. a) How much further will the platform sink if a mass of 50kg is placed on the platform? b) What is the maximum load that the wires can hold before breaking? Homework Equations...

Hello guys , have a question and I can not find the answer. In what units is measured elastic limit ? Thanks A lot !

I understand that massive spinning objects drag spacetime along with their rotation, and that the inner region is dragged more strongly than the distant regions. It would seem that spacetime gets stretched. Does spacetime have an elastic limit, such that it could "break" at some point...

Hi, When we find out the deflection of beam, the factors considered are its geometry (moment of inertia) and young's modulus (E) of the material. As per text Hook's law 'E' is constant only till the elastic limit of the material. Assuming that the stress induced crosses the elastic limit, 'E'...

Homework Statement I'm completing a homework for Young's Modulus and one question asks to estimate the elastic limit for the wire which was used. I can see where this approximately is on the graph I have drawn. When the question asks to estimate the elastic limit, does this mean to...

Homework Statement For my coursework I am to compare how the elastic limit in polyester & cotton varies when the same force is applied to them both. I want to do this because for my coursework I have decided to do why polyester is a good material for football shirts, and why, if it is...

How do I set this up? "The elastic limit of a piece of steel wire is 2.7 X 10^9 Pa. What is the maximum speed at which transverse wave pulses can propagate along this wire before this stress is exceeded? (The density of steel is 7.86 X 10^3 kg/m^3) I know v = \sqrt{\frac{T}{\mu}} so I guess I'd...

Hi everybody. First of all, sorry for my English. It's not my mother tongue. We made the Hooke's Law experiment at school (high school). Everything worked out great. We had to find the spring constant and we did. But our teacher gave us an assignment for extra credits! We have to find the...
