Calculate the maximum vertical point force P that this beam can sustain

[pj33]

A simply-supported steel beam with a vertical point force P is shown in
Fig. 2(a). A cross-section of the beam, which is composed of two identical C-shaped
members bolted back-to-back, is shown in Fig. 2(b). Both C-shaped members have a
uniform thickness of 1 cm. Pairs of bolts are located at a spacing of 0.5 m along the
length of the beam. The beam bends about the x-x axis shown in Fig. 2(b). Each bolt has
a shear capacity of 1 kN, and the yield stress of the C-shaped members is 355 MPa.
Calculate the maximum vertical point force P that the beam can sustain.

Can someone help me solve this, because I am a bit confused.
