Thanks nvn, looking through the beam deflection calculations all i see is a pinned one end and roller the other end, i cannot see a pinned pinned deflection formula anywhere.
Thanks for that mfb, when working out a deflection of a beam then, what is the x, is it the span of the load?
If you have a formula of F*b^2*X^2/6EI*L^3(3*a+b)-(L*a) for a fixed beam, I have everything except x. and what is the deflection formula for a pinned-pinned beam?
Also if nvb said its 88...
Thanks for your help nvn, I really appreciate it, and will have a good go at the deflections, but just want to mention GPa is a SI unit and length the standard SI unit is the metre, just like Density is the kg/m^3 and Force is the Newton.
You have helped me lots in the deflections, and I thank you.
Sorry, I have to model a thin walled shaft with 2 bearings, one at each end, as a simply supported beam, but have to work out the maximum deflection for pinned and fixed at both ends.
The shaft is 100mm outside diameter, with a 6mm thickness of the wall.
The bearings I have to model as both...
Homework Statement
I need to know the correct equations for a pinned-pinned beam and a fixed-fixed beam with 3 point loads(450N, 0.3 from the left,450 0.7 from left and 450 1.1 from the left, the beam is 1.4m long, with maximum deflection and bending stresses
But I have to use the second...
