The column shown is fabricated from two C250 x 30 standard steel shapes (see Appendix B for its cross-sectional properties) that are oriented back-to-back with a gap of 33 mm between the two channels. The column is fixed at its base and free to translate in the y direction at its upper end. Translation in the z direction, however, is restrained at its upper end. A load P is applied at an offset distance of 430 mm from the channel flanges. Use the AISC equations given in Section 16.5, and assume that L = 4.1 m, s = 33 mm, E = 200 GPa, oy = 275 MPa, and (Gallow); = 145 MPa. Offset - distance e P Lateral bracing in z direction C250 x 30 L C250 x 30 Cross section.

Got this wrong. please help and show work then round the final answer to 3 sig figs.

I can't seem to figure out the moment at C and D with the forces being F1=477lb   F2=208lb   F3=284 Can you help me figure out what I am missing here please?

The shelf bracket is subjected to the force F = 336 Newtons at an angle 0 = 25.5°. Compute the moment (in N-m) that this force exerts about each of the two attachment points (screw locations in the figure). Take counterclockwise moments to be positive. a F 2013 cc CC Michael Swanbom BY NC SA Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. Variable Value a 48.0 cm 45.6 cm 4.10 cm The moment about the upper attachment point is N-m. The moment about the lower attachment point is N-m. luk-

Please look at the images for details about the question. (For the second image, find out the correct values for A_x, A_y, and C_y)

final answers are  Problem 1: ΣMA = 1371.93 lb-ft CCW  Problem 2: By = 11,166 lb show the steps to get these answers
