a reinforced concrete beam with a cross section of 250mm x 460mm (60mm steel cover). Use the following properties to calculate what is required: f'c=20.7MPa, fy=344.7 MPa, As=36mm, A's=2-25mm a. Draw stress diagram of the beam section b. Calculate depth of compression block c. Calculate compressive strength of concrete in KN d. Calculate for nominal moment capacity of beam

please show step by step solution. thank you so much!
