If a cantilever beam is subjected to an upward point load at the free end, the nature of the stresses developed will be:
1
tensile above the neutral axis and compressive below the neutral axis of the beam cross-section
2
tensile above as well as below the neutral axis of the beam cross-section
3
compressive above the neutral axis and tensile below the neutral axis of the beam cross-section
4
compressive below as well as above the neutral axis of the beam cross-section
