The number format should change so that when the value is much less than 1 it still displays something other than 0.000. For instance if I work in meters and have a circular beam with a diameter of 0.048m it looks like Ixx is 0. I could change all of my units to mm or something else but that sort of defeats the purpose of having software take care of the menial things.
Yes I agree Daniel. This is a great suggestion. For us we are focussing on functionality so much that we forget about these small types of things.
Yes we are on a much better rounding system now which features scientific notation for very large/small numbers. These sorts of issues should be a thing of the past now.
There is a little problem. We can not add any type of support on the upper surface of the beam. Please try to fix this problem otherwise calculator is efficient.
Thank you
Yes I agree! A roller/pin support may sometimes be on the upper surface. This is a small issue however, we have more important things to worry about for now but I’m sure it will get fixed in the future.
….the shearing and moment equations are all wrong…….thanks for nothing! =C
Yes there seems to be a slight bug with the trapezoidal Distributed Load Shear/Moment Equations. We’re on it. Please check your email!
This appears to only be a problem downward sloping distributed loads. I will announce when this is fixed on our FB page.
Done! The latest updates have fixed these bugs
this calculator has been very helpful, thank you for providing this service. I would like to be able to add supports from the to that’s my only criticism
There is a hover point about each ‘important’ location that displays the values of the curve at that point but one thing that could be useful is to display values on the curves at the cursor location. Right now I need to put an intermediate evaluation point where I think I’ll be interested in before generating the solution.
Maybe to keep the responsiveness of the site high you should require that the user clicks on the curve at the approximate location they are interested in.

Dan
Hi Daniel. This is really interesting. You’re saying that you’d like to be able to put the mouse over any part of the curve so it can tell you the (x,y) coordinate of the mouse? As you are not sure where to put the evaluation point before seeing the solutions/graphs?
Problems like this have been fixed with the new evaluation fields on the solution pages.
Hi there
Thank for a great learning tool. I have 3 suggestions:
1. It would be great to have a calculator that would calculate the Internal Action of Frames
2. The convention BMDs here in AU is to have + below and – above the beam to represent what the bean would look like in reality. It would be good to have the option to see the diagram with this different convention.
3. Internal hinges
Regards
Tim
Thanks for the feedback and suggestions Timothy.
1. We are definitely going to be creating a separate calculator for this one soon enough…
2. I really like this idea. We are from Australia too. The reason that the BMD is like that is because we are taught that the value of shear force at any point is equal to the slope of the bending moment at any point. Hence if the shear force is positive then the BMD must be sloping to the right etc. We may include an option to flip the BMD.
3. We are on this one as well.
Hinges are done! The BMD can now be flipped to cater for the opposite sign convention!
please explain the answer in brief
We are thinking about this one. Thanks for contacting us!
Can we add more than 2 supports on the beam?
More than 2 supports classifies it as “indeterminate”. This sort of problem can be solved with the PRO calculator.
Please check your email (including any SPAM folders) as I answered your email too with the answer you were requesting. Enjoy!
I would like to be allowed editing after solving!
and for an option to see formulas for solved reactions!
Thanks
Yep that is all coming very shortly! Very soon both of those options will be available. You will be able to edit after solving for free. The equations will come only with the PRO calculator though
This is all possible now after our latest updates!
I would like for there to be an option to add a “cut” to the beam. The option to add a hinge would also be nice.
Hi Tula. What would be the purpose of the “cut” be exactly? To split the beam into 2 separate spans? Yes we are thinking about hinge joints. Hopefully in the near future they will be available. Thanks for your input. Highly appreciated!
Hinges have now been added! Enjoy!
It s really really helpful. Thanks a lot!!!
Wonderful!
Amazing tool!!
Nice work!!!
be great of you can have a print section. fabulous software but need to transfer it to other docs
many thanks
We’re on it. Should only be 1 or 2 weeks now
It would be great if there was a possibility to add more than 2 supports.
Hi Stepans. More than 1 fixed support and more than 2 pins/rollers classifies the solution as indeterminate. The solution is much more difficult to calculate in this case. The good news is that we have finished coding this solution and it will be available in the PRO calculator very soon! =)
Anything for mobile devices? Anything for iOS?
Possibly! Are you talking about an app specifically? Or just a cleaner website for mobiles? At the moment the website should be functional on smartphones and tablets although it is pretty ugly we must admit. In the next few months we may look to improve the whole user interface for the site but our first priority is the releasing the PRO calculator.
This calculator show false bending moment diagram for over hang beam. BMD is all positive or negative.
Could you please explain further? Overhanging beam? Do you mean a cantilever?
Dear,
We would like to add this calculator to our site http://www.civilengineerspk.com
How can we do that ?
Sorry but I don’t think that is possible…you can put the link “http://bendingmomentdiagram.com/free-calculator” on your website so that others can use it. They can simply click from your website to this one =)
can u mail me from your id so that we can talk ?
Just sent you an email to your hotmail address. Check your spam/junk folder if you don’t see anything.
Is it assumed that a clockwise moment is positive?
In the reactions tutorial on our site we have taken counter-clockwise moments to be positive. In the end it is up to you which convention you use…you can choose clockwise to be positive. Generally counter-clockwise as positive is most common. It doesn’t really matter — just as long as you use the same direction as positive all the time. Stick to the convention from the start and remain consistent.
UPDATE: The reactions tutorial has been changed so that counter-clockwise moments are positive since this is the norm.
Very useful website for beams, I have found an error on your tutorial page for finding the reaction forces. You have summed the moment around A to equal zero, but there is an error in you equation. It should be -20(2)+By(4) rather than -20(2)+Ay(4). I think you have just got the reaction forces the wrong way round.
Cheers
Yes you’re right! Thanks so much for taking the time to let us know
It is fixed now =)
Hello,
I just find out that it isn’t possible to add a pointload on the same place as a support. this should be possible. Maybe you can arrange this, this will be awesome.
Overal this calculator is helping me a lot thanks!!
Hi Stefan,
This is an interesting one and I can change this quite easily but I’m worried about the results of this change on the rest of the calculator. I will give you a special page where you can try it out. I’ve never really seen a point load at a support which is why the calculator does not allow it…can you please contact us on Facebook and we’ll chat about it some more. Otherwise just keep messaging me here or email me at Paul@bendingmomentdiagram.com
The latest updates have now allowed this
