Understanding Stress Transformation and Mohr's Circle

Ғылым және технология

In this video, we're going to take a look at stress transformation and Mohr’s circle.
Stress transformation is a way of determining the normal and shear stress components acting at a specific location within a body, as we rotate the coordinate system we are using to observe the stresses.
And Mohr's circle is a very simple but powerful technique we can use to represent stress transformation graphically.
We can use Mohr's circle to easily determine the principal stresses, the angle of rotation to the principal planes, and the maximum shear stress.
The principal stresses occur where the stress element is oriented such that the shear stresses are zero. For plane stress conditions there are two principal stresses, which are the maximum and minimum normal stresses.

    Thanks for watching! Mohr's circle really is a key topic in strength of materials. Here are a few useful links: ➡Read the Mohr's Circle article on the Efficient Engineer website: efficientengineer.com/mohrs-circle/ ➡Get access to one-page summary sheets for key engineering topics: efficientengineer.com/summary/

    Abi Rizky Hey man, no. You will learn Mohr’s circle when you take courses like Mechanics of Solids, Analysis of Structures, Concrete Design, or any course that teaches compressive forces on beams, rods and other rigid bodies. I don’t think you encounter those in graduate school. Good Luck!
