A 6 inch X 4 inch rectangular beam is subjected to a maximum shear force of 1900 lbf. Determine the shear stresses at each of the following points on the beam cross section:
(a) a point on the top surface of the beam (and thus the top edge)
(b) a point 2 inches above the neutral plane of the beam
(c) a point on the neutral plane of the beam
Please show all steps and work.
