1. Both rods elongate by the same amount
2. Mild steel rod elongates more than the cast iron rod
3. Cast iron rod elongates more than the mild steel rod
4. As the stresses are equal strains are also equal in both the rods
Cast iron rod elongates more than the mild steel rod
1. maximum bending stress developed in both the beams is the same
2. the circular beam experiences more bending stress that the square one
3. the square beam experiences more bending stress than the circular one
4. as the material is same both the beams will experience same deformation
the circular beam experiences more bending stress that the square one
