    Prying (Heel-Toe) Calculations

    Will Taylor to the rescue... Excellent response. I don't know how we old guys survived in the olden days (1960s or earlier) with just a slide rule, Roark, Bruhn and those CRC tables. A classical hand stress analysis method, considering whether the tension clip is rigid or flexible, is correct...

    Hawker Siddeley design handbook and SOR

    Happy Columbus Day... I have e-copies of the Boeing, McDonnell, Douglas, Lockheed, etcetera stress analysis manuals on a disk. These documents are properties of the different companies. I will not provide same if requested since I have no desire to be locked up with Crooked Hillary. G-pa...

    Interpretation of Material Stress-Strain curves from MMPDS

    ANC-5 then MIL-HDBK-5 and today MMPDS are and were the stress engineers bible for lots of stuff. E. Bruhn covered ANC-5 in his text books. Now, I was in Aeronautics at Purdue years ago and Bruhn was head of the Aeronautics school. Now the guys across the street in Civil and Mechanical...

    Good Vibrations Tutorials

    Cool site monkeydog... There are lots of NASA sites and documents that are directly in-line with aircraft engineering. I came out of retirement in 2007 to work for Jacobs at NASA-MSFC but Obama killed the program in 2010 so I'm retired for good. G-pa Dave [pipe]

    Seeking Description of 14 & 28 VDC Gen Aviation Aircraft Power Supply Charatersicics

    Thanks... "Those were the days my friend". Yep, I still have my CRC tables that my mom bought me in 1958 and Peery's 1950 edition of Aircraft Structures. [pipe]

    Seeking Description of 14 & 28 VDC Gen Aviation Aircraft Power Supply Charatersicics

    MOHR1951... Cargnino! That's a name I haven't heard in a long time. He was one of my professor at Purdue in the early 60s. There was another professor in Propulsion Engineering by the name of Joe Liston who the students called Piston Joe. He had 100s of graphs, nomographs... Oh, Prof Elmer...

    STRESS CONCENTRATION FACTOR, SHORT CHAMFER IN EDGE OF CIRCULAR APERTURE

    Peterson's text on stress concentration factors was, and still is, the bible for stress engineers. There is a 3rd edition that I don't have since being retired for quite some time. R. Roark's "Formulas for Stress and Strain" has some tables for concentration factors... not very complete. G-pa...

    Training - Aircraft Structural Analysis

    I was one of the last students to take a class under Prof. Bruhn at Purdue before he retired in the early 1960's... https://engineering.purdue.edu/AAE/AboutUs/History G-pa Dave [pipe]

    Space Launch System Rating

    If the Constellation program had not been cancelled in the Spring of 2010, the Ares I would be delivering astronauts and cargo to the ISS at this time. Check out: https://en.wikipedia.org/wiki/Constellation_program G-pa Dave [pipe]

    Design limit loads and Structural design process

    I'm surprised no one has responded to your subject but this Spacecraft Engineering forum has few visitors. I've been retired from aerospace for almost 15 years. Working primarily as a stress analysts in the military missile "racket" and various military and NASA manned systems over 40+ years...

    Climate Sensitivity and What Lewis and Curry 2014 Has to Say About It

    Not too worry... WWIII will trump all concerns about climate change (aka global warming) and other extinction events... IMHO. G-Pa Dave [pipe]

    SpaceX Falcon 9

    This Spacecraft engineering form has a lack of visitors... Your article was interesting. Are you the IHS standard guys? Hope the other folks, Orbital Science and Virgin Galactic, resolve their issues and get back on track too. G-Pa Dave [pipe]

    Joggles and Crimps

    Is the "N.A.A." you refer to actually the NCAA... maybe from some old 1930s, 40s, 50s, etc.? In those days lots of empirical tested data was collected and documents. Check out Elmer Bruhn's classic text book which points to NCAA references.

    Would you major in Civil Engineering in 2014?

    Zelgar - I complete agree. What's being taught today in engineering colleges? Back in the late 50s and early 60s when slide rules and engineering handbooks were used, our generation was taught the basics. Today with all this FEM-ing, FEA-ing and CAD-ing the basics get lost. When I started at...

    Would you major in Civil Engineering in 2014?

    No... "My tongue was stuck in my cheek." I'd never work for the local, state or federal governments. However, if you do join the public sector you are general fixed for life. In the private sector today, companies are not offering pension plan so you have to start early planning for...
