The image contains a structural engineering problem involving a simply supported rectangular beam. Based on what I can read, here is a summary of the problem details:

• The beam has a span of 20 ft.
• The beam has a cross-section of 12 x 24 inches.
• It is reinforced for compression with two No. 7 bars, which are placed 2.5 inches from the top surface of the beam.
• It is also reinforced with six No. 7 bars for tension, located 2 inches from the bottom surface.
• The beam has an f'c (compressive strength) of 3500 psi.
• The yield strength of steel (fy) is 50,000 psi.

The question seems to ask for the resisting moment of the beam, using the given reinforcement details and material properties.

Clarifying steps:

• The resisting moment involves calculating the moment capacity of the beam based on its reinforcement (both compression and tension) and material properties (concrete strength, steel strength).
• This would involve using principles of reinforced concrete design, such as the ACI (American Concrete Institute) design formulas.

Do you want me to provide the detailed steps and formulas to calculate the resisting moment for this beam?
