What would indicate correct collimation in a lateral projection of the pelvis?

A circular shaft is composed of three concentric, perfectly bonded cylindrical layers: A (outer), B (middle), and C (core). Each region is made of a linear elastic material and shares the same twist. Applied internal torque in each region: TA = 1000 N.m, TB = 100 N.m, TC = 500 N.m The shear moduli of the three regions are: G = [GA] GPa  ——- for  A G = [GB] GPa  ——- for  B G = [GC] GPa  ——- for  C The outer radii of each region are: a = 0.3  m ——- for  A b = 0.2  m ——- for  B c = 0.1  m ——- for  C Please Don’t Provide a final answer for Question 1
