Learning Goal: To understand the conventions and concepts of torsional deformation for circular rods. The circular rod shown below is subject to torques around the \( x \)-axis such that the angles-ot.twist at each of the sections shown are \( \phi_{A}=0^{\circ} \), \( \phi_{B}=10 \). \( \phi_{C}=-10^{\circ} \), and \( \phi_{D}=-10^{\circ} \). The distances between the sections are \( L_{A B}=1.5 \mathrm{~m}, L_{B C}=3 \mathrm{~m} \), and \( L O D=2 \mathrm{~m} \). Assume that the angle of twist varies linearly between the given points. Part A - Gradient of the angle of twist The shear strain in a circular rod subject to torsion depends on the gradiont of the angle of twist. What is the gradient of the angle of twist in the three sections of the tod? Express your answer to three significant figures in rad/m. The shear strain in a circular rod subject to torsion depends on the gradient of the angle of twist. What is the gradient of the angle of twist in the three sections of the rod? Express your answer to three significant figures in rad/m. In a circular shatt, the torsional deformation results in shear strain y between lines in the axial direction and the azimuthal ditoction. as shown. Several points on sections of the rod are shown below. Rank these points based on the magnitude of the shear strain. Rank the jtems from highest to lowest shear strain. To rank items as equivalent, overlap them.
