What is the Moment of Inertia for a Rectangular Beam under Uniform Force?

[Savage32]

Rectangular Beam-

Cross section
h - dimension in y direction
b - dimension in x direction

If with a uniform force acting on the beam in the negative y-dir, what is the relevant moment of inertia when modeling the deflection u(z): E I (d4/dz4)u =w?

I believe it is bh^3/12, but I am not positive

Thanks in advance for any help.

Yes, you are correct. You are listing the Second Moment of Inertia (Area), which deals with bending stress.
