Question
The cross section and dimensions of a 6 m long asymmetric I-beam are shown. Determine:
(a) The position of the neutral axis relative to the bottom face.
(b) The second moment of area about the neutral axis. If the beam is simply supported at each end and if the maximum allowable bending stress in the beam is 180 MPa, determine:
(c) The maximum allowable central point load.
