Q5 [20] A uniform steel bar is fastened to a vertical steel C-channel of dimensions 12"x2.942"x0.282". A static load of 4000 lbf acts at the right end of the steel bar in the direction with a-45. Select a proper SAE grade bolt from the fine-pitch series, and design a bolt joint to safely carry the static load with a factor of safety 1.9. If you cannot obtain a satisfactory design in one iteration, indicate what you would like to do in the next round of iteration with a clear strategy. But do not carry out any further iteration because of the time constraint. Notes -You must allow adequate clearance to avoid interference with the C-channel legs. -You must arrange the bolt centerline to be at least 1d away from all concerned edges to avoid weakening the member strengths. h F9 2.5 All dimensions are in inches.
