$(26)$ Three bars form an axially loaded system and are subject to the applied

loading as shown. Find the stresses in each bar and the deflection of point D$.$

Bar $1$: Modulus of elasticity of $30,000$ksi, area of $3i{n}^2.$ From B to D$.$

Bar $2$: Modulus of elasticity of $10,000$ksi, area of $2i{n}^2.$ From D to F$.$

Distances BC$,$ CD$,$ and DF are all $12$ inches. The loads are applied exactly at C

and D$.$
