8-48 A vertical channel 152 x 76 (see Table A—7) has a cantilever beam bolted to it as shown. The channel is hot-rolled AISI 1006 steel. The bar is of hot-rolled AISE 1015 steel. The shoulder bolis are M12. x 1.75 ISO 5.8. For a design factor of 2.8, find the safe force F that can be applied to the cantilever.
