## T-beams and Second moment of area

Greetings all,

Given an upright T-beam (really a T when you look at it) with all dimensions given, what is the procedure for finding the second moment of are about the z axis (I sub z)?

Thank you so much.

 Recognitions: Science Advisor Since this is boarderline a homeowork question, I'll try to help without helping too much. Do you know how to find the area moment of inertia for a rectangle about an axis (hint: you have two of them in your problem)? Do you know what the parallel axis theorem is?
 Yes I do know how to find the second moment of area rectangles. But I am not sure of the parallel axis theorem.

The Parallel axis theorem or Steiner's theorem is on any Vectorial Mechanics: Static book.

Thank you all that responded. I understand fully now.
