Structural Definition and 215 Threads

Hey guys, I need setting up this problem. Here it is: A structural member is fabricated from a solid round bar of steel with a diameter D=50mm. If the member is 6.0m long, determine the maximum axial force that can be applied if the axial stress is not to exceed 175MPa and the total...

Tom Irvine at Vibrationdata.com has linked to a book "Structural Mechanics for Undergraduates." The entire book is free to download here: http://www.vibrationdata.com/strength.htm As a side note: If you are at all interested in learining about vibration theory, analysis and related topics...

Last Question.. I promise! a)Using structural formula show the reactions between: i) HBr and 2-propene ii) 1-butanol and 1-propanoic acid. b) How many isomers are possible in (i) c) Name the type of reacion in (i), In (ii) d) To what family does the organic product in (ii) belong? K...

Is the struggle to reach beyond relativity and quantum mechanics, beyond the big bang, possibly its creation and necessity to our logic, the result of structural problems with mathematics itself? The fundamental unit of maths is numbers, is it not? The discovery of zero or its inclusion in the...

What would be the shapes of these molecules? I drew them out but I couldn't still figure out the exact shape names a. SeO_{3} b. HClO_{2} c. NO_{2}^{-} d.ClF_{5}

Alrite. I am currently trying to write a essay on the structure and evolution of white dwarfs but can't really find any decent websites on this topic. anyone know of any reliable sources of info? i have four books on the topic but all seem to differ from each other when it comes to the actual...

I am looking to make some small wheel rims (about 6-8 inches). I know there are currently rims made of aluminum and magnesium. I know steel would work, but what would be some light weight alternatives. I know of titanium, carbon steel maybe?, steel. I am looking for the strongest, lightest, and...

I'm not sure the formula to use to calculate the deflection of a beam. Here's the information I have got. Steel beam is 50 feet long. There is a 6,000 pound load in the middle(all other loads are disregarded. The modulus of elasticity is 29,000,000 psi. Moment of inertia is 850 inches^4...

This is a HW question, and I posted it in the HW section, but no one there seems interested. Perhaps somewhere here would be willing to lend a hand? See the problem in the attachment. I basically don't know if I am on the right track. I started with part a) by trying to find the force...

Hello, I was quite curious about this one here... If I were asked to draw a structural diagram, for example, of trimethylbutane, where would I put the three branches of methyl. When they don't specify the location of the branches what does one do? I'd normally be expecting something like...

Hello, I was hoping someone here might be able to explain to me how to determine electron dot diagrams and structural formulas of diatomic/polyatomic elements and compounds. For example... Nitrogen Tri-iodide ( NI3 ) I know the basics of electron dot structures, but when the atoms start...

Hi, Please read it until the end, before you write your remarks. Thank you. ---------------------------------------------------------------------------- The main idea of Cnator's second argument is to show that the real numbers list can never be a complete list. If we have to...

Noncommutative structural numbers Hi, In the attached address (at the end of the web page) there is a short paper (a pdf file) on noncommutative structural numbers: http://www.geocities.com/complementarytheory/CATpage.html I'll be glad to get your remarks. Thank you (and...

Hi, Take for example these 5 equations: 1 1 1 + 2 = + 2 = + 1 1 1 4 = + 4 = + 4 = + 1 1 1 + + 2 = +...
