How to Determine Stresses Acting on an Inclined Plane | Follow this Procedure to Get Full Score

This video explains how to determine normal and shear stresses acting on inclined planes in the soil element. There are different ways (which are also fine) to do it and thus many students get confused. If you follow this procedure you will always arrive at the correct answer.

The only video that made me understand how to find the angles! thank you

[@omegachong2078]

This helps a lot! Thank you sir!

[@suhsi2287]

If anyone is having troubles with the way the angle is found, essentially you subtract whatever your angle is from 180

normal stress is going towards the object, does not it suppose to be negative.

[@aliridah920]

thank you dr. ❤❤❤❤❤❤

[@AmrAhmed-pj5vw]

I think sir this in case of tension not compression as (shown in video) so should the normal stress then be negative ?

[@RaghvendraSingh-tq3zd]

respect sir

I unable to understand that the direction taken by thita

[@amarbayarjugdernamjil2568]

could you explain the equations those how can be governed from?

[@GeoEngineeringandScience]

This video only explains how to use the formulas related to soil mechanics. The theory on how to derive these equations can be found in textbooks on mechanics of materials.

[@eltariquaye6928]

i must be doing something wrong because this does not work for me

[@jerrylam5050]

Why is the degree 135 instead of 45?

[@GeoEngineeringandScience]

This is just how the formula works

[@tempestandacomputer6951]

@@GeoEngineeringandScience Well that ain't very helpful. Understanding derivations of formulas helps students a lot.

[@tempestandacomputer6951]

You add 90 degrees to the 45 because that way you account from the total angle made from the original x-axis to the new position. In other words, to do these calculations, you rotate your unit coordiante system 45 degrees. Because you do that, you must add 90 to account for it. And remember that you rotate your coordinate system so that SigmaX is normal to the plane you are testing and Tau Y is parallel to it.
