A horizontal rigid bar 𝐴𝐶 is supported by two columns with
pinned ends ( 𝐴𝐷 and 𝐵𝐸) at points 𝐴 and 𝐵. A vertical load 𝑃 acts
at the end 𝐶 of the bar. 𝐴𝐷 has the length of 40𝑐𝑚 and area of 𝐴𝐴𝐷
= 300𝑚𝑚2 while 𝐵𝐸 has the length of 20𝑐𝑚 and area of 𝐴𝐵𝐸 = 400𝑚𝑚2 .
The modulus of elasticity of both sections is 𝐸 = 200𝐺𝑃𝑎. The
length of 𝐴𝐵 = 40𝑐𝑚 and 𝐵𝐶 = 50𝑐𝑚 as show below:
