Question

4. The following shaft is simply supported at A and B,
with bearing A as the thrust bearing (i.e., fixed in
both the x and y directions), and bearing B is free to
move in the x direction. All dimensions are in mm.
The shaft diameter is "d".
Find the largest normal stress at x = 40 mm.
Combining the stresses using M is allowed for this
res
problem because the shaft is rotating. Find the
shear stress at this same location (neglect
contribution from transverse shear). Sketch the
stress element showing this state of stress.
