True! I compared mine with the DC10 allowable and it's higher. Thank you. Damineh

I have been looking for allowables for NAS1097AD for a while now. As mentioned here, it can't be found in MIL-HDBK-5. Today, I came across a thread from 2004 in which SparWeb participated in and I believe you were sent Grumman and Douglas test data for this fastener. Is there any way you could...

I am trying to find the: - bath solution (chemicals), - bath temperature, - immersion time, and - end colour of the product for each of these finishes: - Black Oxide, - Electropolish (S.S.), - Hard Chrome, - Decorative Chrome, - Electroless nickel (S.S.), - Zinc Phosphate, and - Magnesium...

We were barbecuing on our camping trip last Saturday and our stainless steel meet holders (cooking tool) were left in the fire. My friend asked us to take it out because it would melt. I started arguing that it wouldn¡¦t, as the melting point of stainless steel is much higher than the...

Yes I have learned a lot from this one question I had. I am very pleased to have joined this forum as I learn things I wouldn’t learn from books. Heh yeah that lady and my supervisor must have the same background! I have taken all the material courses offered at school including electives such...

Thank you all very much. Unfortunately, my supervisor who has a PhD and PEng, is so sure of himself that doesn't listen to what I suggest. I told him about magnetic strength of 300 and 400 series and that magnet wouldn't be the best method to examine stainlessness of steel, the first day he told...

What if the company doesn’t trust the supplier? They build us bearings and assemblies and sometimes they cheat! Is there any test that can identify the grade? PS. Did I do anything wrong??? I have read that page before and don’t think my thread was a bad one :(. This is regarding the “Wanna...

My supervisor had taught me that I can check whether a piece of metal is stainless steel or not using a magnet. That’s all! 2 days ago, we had a rusted bearing and when he checked each and every component of the bearing with a magnet, he assured everyone none of the parts were stainless steel as...

Ok let me re-write my question. This is the same fan I have used in my above question: I have a fan. It¡¦s running for hours (reaching steady-state temperature). As I increase the fan speed (rpm), the airflow rate is increasing. The increase in airflow rate, increases the dissipated heat of the...

I am working on a fan system. The airflow rate through the fan will increase as you increase the rpm: Q = (öND3) sin (á)/350 ö= 0.1 D=1 á=21 degrees How would the temperature change as Q changes? Let’s say we have a few objects behind the fan which are affected by the flow rate increase...
