| Q.45 | At a point in a stressed body there are normal stresses of 0.5 N/mm2 (tensile) on a vertical plane and 0.4 N/mm2 (tensile) on a horizontal plane. The shearing stresses on these planes are zero. Determine the normal stresses on a plane making an angle 30° with the vertical plane. | |

| 2. 0.525 N/mm2 | ||
| 3. 0.325 N/mm2 | ||
| 4. 0.475 N/mm2 |
Correct Ans: 4
