Consider the following statements:
Two beams of identical cross – section but of different materials carry same bending moment at a particular section, then
1. The maximum bending stress at that section in the two beams will be same.
2. The maximum shearing stress at that section in the two beams will be same.
3. Maximum bending stress at that section will depend upon the elastic modulus of the beam material.
4. Curvature of the beam having greater value of E will be larger.
Which of the statements given above are correct?
(a) 1 and 2 only (b) 1, 3 and 4
(c) 1, 2 and 3 (d) 2, 3 and 4
