Trevor, thank you very much for your time in writing thorough responses. I think the [M.L/T^2] portion was tripping me up.

Sooo.....when I weigh the piece and the scale says 0.172 Kg, that equals 1.687 Newtons of force? Thus: [((414.6 * 0.5085^2) / (1.0279 * 0.019)) ^2] * [1.687 / (0.5085 * 0.051 * 0.019)] = 103,144,928,394 N/m (103 GN/m)....which is not a unit of pressure....(scratching head).....umm....where am I goin...

Hello everyone, I've been trying to calculate the Young's Modulus of some bracing material (Spruce) using equation 4.4-4, and am having a bit of a fit with it. Using equation 4.4-4, the resulting units for "E" end up being g/mm instead of g/mm^2. So, I’m a bit confused how to get that into GigaPasca...
