Problem: A rectangular aluminum beam shown below constitutes part of a rotating calendaring machine attached to one edge is a narrow blade loaded uniformly along the length at the angle shown. Furthermore, the ends of the beam are subject to an external torque since it is also used as "driveshift" to power other components attached.
a. Determine the maximum moment to locate the maximum bending stress and its location.
b. Find the maximum shear stress and its location.
c. Find the total angle of twist from one end to the other (in degrees).
d. Compute the maximum von-Mises stress by examining stress combinations at likely locations.
e. Redesign the extrusion's wall thickness to limit twist to 1 degree.
f. Compute the neutral axis orientation (draw it on the diagram).
g. Compute total deflection at the center of the beam knowing that δmax = 5wL*/384El
