QUESTION 02 Figure Q2(a) shows a stainless-steel beam ABC with a uniformly distributed load along ABC. The beam is pin supported at point A and B. The Modulus of Elasticity, E of this beam is 200 GPa. (a) Draw the shear force and bending moment diagrams for the beam and indicate all important points on the diagrams. (b) If the cross-section of the beam is as shown in Figure Q2(b), determine the maximum bending stress at points P and Q and identify its type (compression or tension). (c) Calculate the maximum transverse shear stress at point R (joint between the flange and the web). (d) Without calculation, what effect does it have on the transverse shear and bending stresses calculated above if a material of a lower value of Modulus of Elasticity is being used. State the reason for your answer.

Figure Q2(a) shows a stainless-steel beam ABC with a uniformly distributed load along ABC. The
beam is pin supported at point A and B. The Modulus of Elasticity, E of this beam is 200 GPa.
(a)
Draw the shear force and bending moment diagrams for the beam and indicate all important
points on the diagrams.
(b)
If the cross-section of the beam is as shown in Figure Q2(b), determine the maximum
bending stress at points P and Q and identify its type (compression or tension).
(c)
Calculate the maximum transverse shear stress at point R (joint between the flange and the
web).
(d)
Without calculation, what effect does it have on the transverse shear and bending stresses
calculated above if a material of a lower value of Modulus of Elasticity is being used. State
the reason for your answer.
