Abstract:
Measurements of the attenuation curves of low energy x-ray beams are used in this work as a functional description of such beams. Measurements of the transmission curves through aluminum made with a low volume ionization chamber have been used to predict transmission curves through copper. The results are compared with the data of attenuation in copper measured with the above-mentioned ionization chamber, and also with calculations of attenuation in copper made from reference x-ray spectra and tabulated values of the mass attenuation coefficients of copper.

Equation of the Elastic Curve
Consider a cantilever beam with a point load at its free end (for instance, a diving board). When analyzing beam deflection with small slopes, the shape of the beam's elastic curve becomes key. The governing equation for this analysis involves the bending moment and the beam's flexural rigidity,...
