What is the difference between these two grades, if any? And what could be the reason for picking one over the other?
As far as I could see, F55 has tungsten in its chemical composition.
ASTM A370 specifies a range of impact energies that can be used as an acceptance criteria for a Charpy impact test. How do you decide what impact value to use for a particular specimen size? Some material specs state the impact energy acceptance criteria and temperature that the test has to be...
I was looking at calculating the bending stress on bolts due to a combined load and came upon this link http://www.roymech.co.uk/Useful_Tables/Screws/Bolted_Joint.html
Could someone explain the formula Fnt = ( Fv. Rv + Fh. Rh) . Vn / (V1^2 + V2^2....Vx^2)? Especially the denominator. I've...
How much does the mechanical properties of polymers like PTFE or PEEK change depending on the process it was formed from? For example a billet formed from extrusion as opposed to a billet formed from moulding.
We buy in valve seats to an internal spec which says that the raw material can be...
What exactly are meant by tangential stresses in the context of Appendix 2. I've just done some calculations but I'm trying to understand what direction these stresses act in. Are these the forces caused by the inward bending of the flange due to the bolt load?
How can I get the final deflected shape using the method of superposition? My cantilever has 3 spans with 4 supports. See the pic attached which I've drawn using my new-found paint skills [bigglasses]. At the fourth step, I only know how to get the deflected shape when either of the two middle...
Hi,
I'm trying to calculate the reaction forces on a vertical continuous beam (seawater caissons on offshore platforms if anyone's interested). I'm doing this in Excel. So far I've been able to calculate everything up until deflections if the beam was a cantilever but I'm not sure how to...
