I didn't understood the last part where you find the stress of transformed unit. Haven't we transformed the steel into brass when we increased its crossection by 2 times .
1:24 he is clutch
How do you go by transforming the entire structure into steel instead of brass as you did
great one
if the c distance was different, how would you have calculated it?

Yeah u are right. That's exactly what I wanted to say too
Great video!!
Thanks, I see you guys have some too! Keep it up!
How about circle shape cross section? Obviously the c will increase when we transform it.
What if I have a cylinder with a steel core and nylon shell? Then n=132, but I can't just multiply that with the width of the cylinder...
Niko D you need the multiply the thickness factor
What this video is
Isn't it the formula for moment of inertia is bh³/12 +Ad²
??
That's the parallel axis theorem. It's used when you have different shapes that all connect as one beam. i.e., t-beam, I beam (w-beam), etc.
That's for parallel axis theorem
E is diffrent for each part, you cant just combine the E.
you adjust the width of the steel to give it equivalent properties to brass. Then you can use the same E
