engineering recuitment NHPC JE & THDC JE 2023 Mock Test Strength of Materials Simple Stress and Strain
In an unsymmetrical beam under bending, the maximum compressive stress at the top is 1200 MPa and the maximum tensile stress at the bottom is 300 MPa. If the beam is 80 mm deep, the neutral axis from the top surface will be:
1
60 mm
2
64 mm
3
40 mm
4
32 mm
