oh ok thanks. so you're not meant to take the moment of the two points? An example i saw did it that way i think so i thought i'd give it a go. oh well, back to the drawing board!
ps. you calculate the moment of the distributed load by multiplying the magnitude by its length and then placing a...
Heres my attempt at using method of sections to write the equations:
I
0<x<a
v=-7.5kN
m=-20kNM
II
0<x<0
v=-7.5kN + 10x
m=-20kNm + (10x^2)/2
III
v=-7.5 kN + 10x + 30kN - 21.2kN
m=-20kN + (10x^2)/2 + 30kN.x -21.2kN(6)
As you can probably tell I'm struggling pretty bad on this...
Hi Guys,
I'm having real difficulty trying to understand shear force and bending moment diagrams - both cantilever beams and supported ones like below. I've given it my best shot to solve the reactions at the points and would greatly appreciate any help on how to form the diagram and the...
