It's Reinforced Concrete problem. Can you give me a solution please? It's urgent

1. (25 pt.) Prove that the maximum shear stress in a beam of rectangular cross section is 50% larger than the average shear stress VIA. VQ Note: The shear formula, 7=- Ib . Your answer must start with the shear fomula. Answer including the simple formula without derivation won't deserve any credit. 2. (25 pt.) For given loading and geometry conditions as shown in Fig., the modulus of rupture (f.) of M 3P rectangular concrete beam can be calculated using the following equation f, =4y=. Derive the equation for f,. L/3-h L/3-h L/3=h 3. Calculate (1) (25 pt.) The maximum bending moment Msax (2) (25 pt.) The maximum shear force Vmar B -b- 7. elea
