54 . A rectangular beam 20 mm wide by 120 mm deep and a point
A is 20 mm above the centerline of the beam. Assume the 50
kN loads acts at the centroid of the cross section.
a. Compute the max. shearing stress at point A when x = 250 mm
(ANS. 38.20 MPa)
b. Compute the max. normal stress at point A when x = 250 mm
(ANS. 72.58 MPa)
