Learning Goal: As shown, two composite columns of steel and concrete are used to support a rigid platform. The columns are cylindrical, with a steel bar encased in concrete. The outer diameter of each column is de = 20 cm. The steel in the left column has a diameter of d₁ = 10 cm. A load of P = 74 kN is applied with L₁ = 1.8 m and L2 = 2 m. The height of the columns is h = 2 m. The moduli of elasticity for steel and concrete are Es = 200 GPa and Ec = 30 GPa, respectively.

Question

Part A solved is 38.9 kN

please solve remaining two parts I've been having issues on, middle part was shaded because I have that concept down

Express your answer to three significant figures in kN.
Part B - Determine the deformation in the left column The steel and concrete in the left column are bonded so that there is no slip. What is the deformation in this column due to the applied load? Express your answer to three significant figures with the appropriate units. Calculate the required diameter of the steel in the second column پیار The design requires that the platform remain horizontal. Because the external load is not centered, and the column forces are not the same, the diameter of the steel portion of the second column must be calculated. What diameter should the steel portion of the column on the right have so that the platform remains horizontal when the load is applied? Express your answer to three significant figures in cm.
