Thank you all for your replies. I am familiar with the torque of the nut procedure to torque HSS bolts and I know the torque wrench is not a good method. However, some people have been using this method (torque wrench) for a long time and it is a bit hard to convince otherwise. I will try again

I am sorry I had to post this here, but I didnt get much replies in the fastening section, I hope you can help: In Australia, to follow the standards AS3990 and AS4100, what should be the torque values for HSS bolts (grade 8.8) using a torque wrench? For example I think it should be 580Nm for...

Hi all , In Australia, to follow the standards AS3990 and AS4100, what should be the torque values for HSS bolts (grade 8.8) using a torque wrench? for example I think it should be 580Nm for M20 galvanised bolts . However everybody seems to use 370Nm I have calculated as follows for M20: 1- T =...

a crane girder made of welded plates was accidently dropped during manufacturing and it was deformed in the lateral direction. in other words it now has like a camber affecting the bottom and top flanges laterally. it is like a permanent lateral deflection... it is still good for...

It is always better to keep your mouth shut, but if you are in a company where practically everyone is a rat, should you join the game or not?

Thanks hokie66 one more question, do you happen to know of any references that deal in detail with girder design of overhead travelling cranes (made of welded plates)? something that covers welding, fatigue, torsion, warping... It is just very hard to find any material related to this subject...

Dont come to Australia, i think it is the worse place for an engineer especially a foreigner. I have been here for 3 years and I can tell you it is very hard to find a job and if you find one you will really struggle. Dont belive what they say about engineers in high demands, it is all lies. I...

Hi all I am designing overhead cranes single and double girder. For the lateral loads on the girders due to the crane accelerating or decelerating in the long travel direction, should we take the girder to be rigidally or simply supported to the end carriages? or maybe partially rigid but i...
