Heaviside function or singularities function

Click For Summary

Homework Help Overview

The discussion revolves around the Heaviside function and singularities functions, particularly in the context of mechanics, specifically for drawing shear stress and bending moment diagrams.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants inquire about the meaning and application of the Heaviside function in mechanics, specifically for shear and moment diagrams. There are requests for recommended resources and clarification on whether certain textbooks are appropriate.

Discussion Status

Some participants have suggested specific textbooks as resources, while others have provided links to websites that may assist in understanding the calculation of shear stress and bending moments using the Heaviside function. There is an acknowledgment that knowledge of these functions is not strictly necessary for creating shear and moment diagrams.

Contextual Notes

There are repeated requests for online resources and guidance on the topic, indicating a potential lack of accessible information on the specific application of the Heaviside function in this context.

Does anybody knows heaviside function or singularities function such as <x-a>^n ;n=1,2,3... for mechanics

i wish to know what does this mean and how to draw the shears stress and moments diagramusing this function.any recommended websites for this is appreaciable too


thanx

Hi, sure what do you want to know about it specifically?

Hibbeler is a good source.

Side: He is not talking about the heavy side function for laplace, which is what I initially though. Right?
 
ya,i mean we need this to draw the graph for shear stress and bending moments in mechanics,any source recommended??
 
You can look for either Hibbler or Beer-Johnston for information on it. Both are sufficient.

Note: You do not NEED to know these functions to make shear/moment diagrams. You can make them without it.

You can try google or yahoo.

besides,those boks recommended up there,are there any links to websites that teach how to calculate the shear stress and bending moments using the heaviside function as stated above ??

This might help - http://physics.uwstout.edu/StatStr/statics/

and

These might be useful for those learning about beam diagrams with loads/forces, shear and bending, and moments -
