The length of rolled steel channel in Figure 2 is fixed rigidly at one end and is free at the other end

and is subjected to an axial load. It has a flange width of 93mm (A) and a depth of 48 mm (B).

Both the web and flange have a thickness of 8mm (C). The modulus of elasticity is 208 GPa and the yield stress is 290 MPa.

Determine the horizontal distance to the neutral axis from point P (left is positive, answer in mm).

Determine the vertical distance to the neutral axis from point P (up is positive, answer in mm).

Determine the 2nd moment of area around the horizontal neutral axis (answer in m^4).

Determine the 2nd moment of area around the vertical neutral axis (answer in mm^4).
