For someone a part of the staff, you don't know your physics very well. I will not be returning to THIS site.

My first answer was correct and as a result I got the question wrong since I put #1. Thanks, MENTOR.

That's why I'm so confused, all parts of the beam contribute to it's strength

if the beam is standing like an I, the weight is on top of it with shear (vertically downward force) force in the middle of the top flange

oh my godddddddddddddddddd I'm just trying to finish this assignment and y'all tripping 1) Its compression area is located on the top of the I beam. this one is true because that's where the weight is 2) Its tension area is located on the top of the I beam. no, the bottom is where the tension...

I really don't know and that's why I posted the question.

I wouldn't be asking if I knew, haha

Then what's the answer? There are only 5 choices

Homework Statement Why is a steel beam shaped in the form of the letter "I" still strong enough to bear a load? 1) Its compression area is located on the top of the I beam. 2) Its tension area is located on the top of the I beam. 3) Its neutral area is located on the top of the I beam. 4) Its...

So how would I do that?

So in a different equation using some of the same values, say, An electron is accelerated to a speed that is 99 percent the speed of light, and is moving through a 2-km-long tunnel. Could I calculate the length of the tunnel in the frame of reference of the electron or is that too irrelevant?

Homework Statement An electron is accelerated to a speed that is 99 percent the speed of light, and is moving through a 2-km-long tunnel. The rest mass of the electron is 9.11*10^-31 kg. What is the mass of the electron at this speed? c= speed of light Homework Equations t= (tsubscript(o))/...
