JL222 Hi jl. Not too sure what you are getting at or the meaning of "swaning". The subject if this thread is a spread sheet created by Mr. Panic. One of the notes in cell O4 says the contents are multiplied by 100 million. I would like to know what the units are. |

"Dimensionless units" to quote Blair - just for comparison, and a multiple is used to make the numbers manageable.

I'm going to include selections for steel, aluminum and titanium once I'm a bit better at Excel (trying to learn software at my age is slow going).

That is a pretty sophisticated Excel sheet from someone that is supposedly "learning" the software.  Many thanks for the updated version and the work being done. Any chance you could do one to calculate bolt strength for tensile and shear?  |

I'm pretty sure that's already out there.
I don't enjoy this stuff, I only made it up because I couldn't find anything except the math (I started writing car calculations by hand when Eisenhower was President). As all you MS Office people know, the "help" files are written by and for the people who wrote the program, and are almost useless to anyone else.

I'm pretty sure that's already out there.(Snip . . . ) All the CAD programs have a bolt calculator feature embedded within. However, not having a robust CAD system, I was looking for something standalone. Agree . . . I'm sure they are out there. I'll start googleing and report back here. Thanks for all your efforts to-date. |

Here are some on-line calculator programs related to bolts and fasteners. (1) 30 Free Trial. Various prices for one year subscription or unlimited licenses available. Look for "bolted connections". Click on " products" (left side) then down load it from here then bolted connections in middle of page. http://www.mitcalc.com(2) Free. Look under online calculators on the left side of the page. http://www.futek.com/boltcalc.aspx(3) 23,585 on line calculators covering every subject you can think of. Look in the Engineering Center under mechanical Engineering. There are a few bolt fastener programs. Careful! you could spend your life here www.martindalecenter.com. (4) Nice chart. Suggested starting torque values with proof and clamp loads. http://www.portlandbolt.com/Documents/Portland-Bolt-Bolt-Torque-Chart.pdf |

I just got an email reply from the author of the MIT software (no. 1 above). The $29 cost of the Bolted Connections program is good for unlimited time. You don't get a CD. It is a download.
