We have build a few storage racks in the shop. I need to calculate the load carrying capacity of these racks. The quality of the welds can be assumed to be good. Is there a formula I can use to do this? I would really appreciate your input here. Thank you.

"Now, due to stress/vibration, one of the connections is fractured...meaning shaft breaks off. Now, every connection is torqued to a certain value. Due to the drilling condition it is torqued further to a point it breaks." Sorry for the confusion. The drilling string (..or the rotating shaft)is...

I need help with the concept of cyclic stress. Suppose a drill string is drilling a hole. The string is made up of number of connections along it's length. Now while drilling, the drilling conditions are difficult. Say the drill bit is having trouble drilling through the formation. This will...

Has anybody done well testing using CMG's IMEX??? I am trying to model a simple reservoir with a horizontal well in the centre and match the production data with the solution proposed by Aziz & Babu, and Goode et al. The problem is for some reason the production data doesn't match any of the...

I need help with the concept of cyclic stress. Suppose a shaft(...or drill string)is drilling a hole. The shaft is basically rotating with the drillbit in contact with the substance being drilled through. The shaft is made up of number of connections along it's length. Now while drilling, the...
