Ok will do, thanks for your advice.

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.

About the First Force of 450 N being at x = 300mm, does this mean the 2nd Force is 700mm and the third 1.1 m at x?

Cheers nvn for the help and everybody else on the forum really appreciate it.

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...
