I am designing a roof which is 5 metres wide and 10 metres long. the total weight it has to support is 20,000 kg.
there will be two I beams spanning the 5 metre width, each i beam is 3.33m apart.
what dimensions should i use for my i beam?
any help would be massively appreciated, is...
I have a moment value: 921.84 KNm which I have to divide by a stress: 275 N/mm^2
What conversion could I do to get this in the form of cm^3?

An aerofoil (chord c = 0.152 m; span b = 0.30 m; NACA 0012 section) is mounted in a drag
balance. A comb of Pitot and static tubes is mounted downstream of the aerofoil. Tubes
numbered 5, 12, 21 and 28 measure static pressure, while the rest measure Pitot (stagnation)
pressure. The tubes are...
it's the measurement of wake traverse behind anaerofoil, the pitot static tube is upstream and connected to a manometer, whilst the rest are pitot (stagnation) tubes and are located downstream and also connected to a manometer
Referenced pitot pressure = 107 (mm) referenced static pressure = 525 (mm)...
find referenced dynamic pressure by subtracting static pressure from pitot pressure and converting to Pascals...
how on Earth do you convert it to pascals?
limits from τ=0 to t
∫τsinωτ dτ
answer: [-τ/ω + 1/ω^2(sinωτ] limits τ = 0 to t
= -t/ω(cosωt) + 1/ω^2(sinωt)Could someone please explain the steps? is this an integration by parts method??
when i attempt integration by parts, with u = τ & dv = sin(ωτ) dτ
I get the following...
Use the Laplace Transform of f (t) = t2 sin 7t to find the Laplace Transform
of f' (t) = 2t sin 7t + 7t2 cos 7t
also note that:
the laplace transform of t^2 sin ωt = (6ωs^2 - 2ω^3) / (s^2 + ω^2)^3
I don't even know how to approach this so any help whatsoever would be hugely appreciated
If a cubic function satisfies f(0) = -32, f(1) = 0, f(3) = 10 and f(4) = 0,
use cubic interpolation to estimate f(2)
I'm not sure how to approach this since I have only ever done quadratic interpolation and linear interpolation, is it just an extension of the lagrange interpolating...
Here is the correct answer: 2x^3 - x^2 + 4x - 5
My attempt only gives me one cubed term and the other terms are also marginally off, any help on who can show me how to get the correct answer will be hugely appreciated
here is the answer:
36/60 = x/.8660
60x = .8660 x 36
60x = 31.176
x = .5196
however, where does the value: 0.8660 initially come from?
any help would be appreciated
