1. The concrete post is reinforced using six steel reinforcing rods, each having a diameter of 20 mm. Determine the stress in the concrete and the steel if the post is subjected to an axial load of 900N.The Young’s Modulus of concrete and steel are, Ec = 25 GPa, Est = 200 GPa, respectively.
2. Determine the moment produced by force F about the diagonal AF of the rectangular block. Express the result as a Cartesian vector.
3. Replace the force and couple system acting on the frame by an equivalent resultant force and specify where the resultant’s line of action intersects member AB, measured from A.
