Heaviside function or singularities function

  1. Jul 13, 2006 #1
    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??

    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 ??

    thanx

    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 -
