I need some advise with a calculation.
I have 2 round components fixed with a threaded bush.
I want to find a good width for the H dimension.
Do you think Checking the stresses as S = F / (π*D*H) can give a good results or do you have some better calculation method?
Thank you
The same applies...
Hello
at work we had a problem with some pieces.
We made 4 pieces like the picture below using a oxycutted plate th. 650 mm material 1.0577.
We machined a hole Ø500 +0.1, but after few weeks the hole has an eccentricity of 1 mm.
Can the cause of this be residual stresses inside the material...
Hello, I'm struggling with a force problem.
I have a system where a mass P, connected to rod od variable length L. The mass is guided to move on the circumference 31500 mm.
To lift the mass I apply a force of 1700 KN on the same direction of the rod.
What I need to find is the force componet...
Hello,
recently I had the a problem with a bolted flange. After a repair some of the screw head pop out (see the picture below).
Is it possible that the failure is due to a too high torque during bolting-up?
All the damaged screw broke at the base of the head.
The screw are Socket Head Cap M24...
Hi,
I'd like to make my calculation sheet more formal.
Some one has a reference for the calculation of non-standard-thread resistance?
I use some basic formulas but I don't have a reference of some norms, textbook,...

Hi,
I have a problem with one of my project:
I'm building a movable cover for my machine, see image below.
I want to move this with a pnematic cylinder. The cover is normally opened and the cylinder need to push it colsed.
The problem is that when I give pressure, the cover close way too fast, I...
Hi,
I need some help with my problem:
I have an hydraulic cylinder filled with a volume V of oil.
I apply a force F on the piston to push the oil throuh a hole d.
How can I calculate the time for the cylinder to be empty?
Thank you
