1. Two rectangular steel plates are used to support 6kN load
as shown in Fig. 1. The cross sectional area for plate AB
and BC are 400mm2 and 600mm2 respectively.
Determine
a) Free body diagram
b) Internal forces in plate AB and BC
c) Stresses in plate AB and BC
d) The elongation of the plate BC if BC = 500mm
Given E 200GPa (Modulus of elasticity)
