A rectangular beam of length 702mm has a width of 132mm and a depth of 301mm. Compression steel bars are placed at a distance 98 mm from the extreme concrete compressive fiber. The beam supports service dead loads of dead load (16 KN/m) and live load (24 KN/m). Reinforced with 4 25mm tension steel bars and 4 12mm tension steel bars f′c = 42 MPa fy = 519 MPa 1. Solve for the height of the neutral axis measured from the extreme compression fiber. 2. Solve for the design moment. 3. Solve for the strength reduction factor.

Question
A rectangular beam of length 702mm has a width of 132mm and a depth of
301mm. Compression steel bars are placed at a distance 98 mm from the extreme concrete compressive
fiber. The beam supports service dead loads of dead load (16 KN/m) and live load (24 KN/m). Reinforced with 4 25mm tension steel bars and 4 12mm tension steel bars
f′c = 42 MPa
fy = 519 MPa
1. Solve for the height of the neutral axis measured from the extreme compression fiber.
2. Solve for the design moment.
3. Solve for the strength reduction factor.
