You just take an example as rect section with A=17.6*10=176 mm2 and your I section too has same area of 176 mm2.
Calculate moment of inertia of rectangular section I = bd3/12 = 1466.66 mm4
For I section, Width of both flange = 20 mm, thickness of both flange = 4 mm, web length=16 mm, web thickness = 4mm. This gives you the same area A=176 mm2
Now Calculate moment of inertia of I section I =8938 mm4 (Do it from any online converter or by calculations)
Now compare both Moment of inertia, I section has approx six times better moment of inertia as compared to rectangular section. Put up this moment of inertia values in deflection and bending stress equations and try to compare both. This is because the material is put up in such a way to get maximum moment of inertia with minimum material and min weight. Finally this is the reason why I beams are preferable over rectangular beams
Once Put up this moment of inertia values in deflection and bending stress equations and try to compare both. you will get it in sec
Upside-down helicopters fall until they turn back over. Sometimes they don't turn back over, and they crash.
Yes.
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.
a magnetic casting is what goes over a magnet
Over the seat
none. circular columns are better than rectangular ones.
preferable you should do it in person, but in my opinion either is fine
integrated card
Yes. It is preferable over trying to refreeze raw thawed chicken.
Well a V-notch gives better accurate results when compared to rectangular notch.
by default any float value is double
yes you can... do to the patriot act they can pull ya over for anything and say they have probabel cause but you not gonna get sighted for it
because the sun beams directly over the equater
The clue is " OVER THE TOP OF" metal sinks windows metal roof flashing metal beams The only possible answer is OVER THE TOP OF WINDOWS
Find a new accountant with tax planning experience. Personal recommendations are preferable over the yellow pages.
Actually if a job is too dangerous it is often preferable to have a machine take it over if the machine can be built to do it.
Unlike a monochromator, polychromators outputs multiple beams over a range of wavelengths simultaneously.
