Hi good evening Can you help me to answer this question please. I really need it before 8pm this evening. I hope for your kind consideration and help. especially  16-18.

- A W12 x 28 is used as a crane runway girder as shown in the figure. The girder is on a simple span of 9 m. The crane wheel imparts a vertical load of P = 90 kN and a lateral load of H = 7 kN. A standard 490 N/m rail will be used. Use A 36 steel. Allowable stresses are Fx = 0.6 Fy and Fby = 0.75F,.
