Superb Bending moment calculator but please add function like ”all calculation with diagram. I hope positive responce.

Thank you for your feedback. These tutorials have been adjusted. However, I do not agree with your point about the summation of the moment about point B in the reactions tutorial. The sign convention was that counter-clockwise moments were positive. So it is correct to say: 0 = 20(2) – Ay(4). Thanks again.

Hi, first let me thank you for the free online calculator. It has been useful.

However I am looking at your tutorials (not yet finished reading) but I found a few possible mistakes you have made and a typo so far:

http://bendingmomentdiagram.com/tutorials/what-is-bending-moment/
it will cause the ruler to bend. At the end where a force is applied will experience the greates bending moment.
I believe it should be “will experrience the GREATEST” bending moment.

http://bendingmomentdiagram.com/tutorials/calculating-reactions-at-supports/
The first equation: Summation of Moment at B = 0 = 20(2) – A(y)(4) —- this is a summation, I believe it is confusing to use ” – A(y)(4)” . It should be more correctly to write as
Moment at B = 0 = -20(2) + A(y)(4) (you are taking downward force negative in part 2, it is you stating that we should stick with same sign convention) although the two equations are essentially equal.

Thanks for the attention, again, the calculator is excellent.

Great effort and really helpful! It would be much better if you give step by step solution to problems.

Hi Gerald,
This can’t really be done because the calculator uses different methods to how it is done manually or by hand.

Could you just show the working out as well to help compare with individual calculations

Hi John. If more people request it then we’ll gladly take the time to add it.

Cheers

Hello, I need to work with stepped shafts. I used to use a program called Beam II that could calculate the deflections at all points along the shaft. For now I can get the Moment of Inertia off my cad model and do a hand calculation at selected points to obtain deflections. Adding multiple beam sections would be most helpful. Could you make sure to add stepped shafts to your program?

Hey Pradeep. Yes this is a feature we are working on. Multiple beam sections should be available in the near future

Hi i find this very useful. just want to give you an example. take a beam 9m long ,I-beam depth is 130mm for 1st 2m’s then 180mm deep for 3m’s then 300mm for next 2m’s. if i can enter the moment of inertia value @ each depth of the section to calculate stress & deflection better. i would really appreciate if you can include this onto your program. thanks guys.
