For the frame below, please answer the following questions (all members are A-36 steel). Take allow 165 MPa and Tallow 100 MPa. Neglect the weight of all members. The connections at B and C are pinned connections. If you need any additional information, make assumptions, but make sure to include your assumptions in your final report and your presentation. 4 m 2.2m--> 75° w=1.5 kN/m 1.2 m 4.5 m. 1.8 m m4 kN/m F=10 kN F= 20 kN B A-A 60° E M=4.5 kN.m M N Section A-A 2 m 1. Determine all reactions. Note that the connection at point A is a pinned connections and the connection a point F is a fixed support. 2. Determine the internal forces for all members. Draw the axial, shear and moment diagrams for each member. 3. Considering the types of internal loads in the members, describe the different types of stress that can occur in each element.
