Cantilever beam question!

  1. Mar 7, 2007 #1
    I need some help. I writing up a lab report and im not sure how to define the equtaion i took down in my notes.

    deflection = (4F/Ebh^3) * L

    Im not sure if this is the right eqution.
    If so can some one please tell me what the varibales: E, b, F and h are.

    I imagine F = force or load, E = Elastic or Young's modulus.

    L is probably length, but the maximum deflection is proportional to the cube of the length.

    b might be thickness (lateral), and h might be height.

    What is the cross-section and how does one calculate the moment of inertia for this cross-section?

    You're in the wrong place. Delete this and put it in the homework section.

    Come on... jesus, b-base h-height L-length.

    If you dont know what F and E are.....sad.

    b.t.w. bh^3 looks alot like MOAI to me.
