1) Consider the truss structure made of 5 members connected by pin joints at A, B, C and D. This truss has pin and roller supports at A and B, respectively and is carrying a load of 100 kN at point D. Members AD, BD, CD and BC are 1 m long. (a) Calculate the reaction forces at A and B. (b) Using only 1 equilibrium equation and the method of joints, calculate the force in member AD. (c) To calculate the force in CD using the method of section and considering only one moment equilibrium equation, which section is to be considered? Draw the free body diagram of the appropriate part of the structure, and indicate about which point the moment equilibrium equation is to be considered. Circle the right answer. (d) Evaluate the force in member CD. (a) 5 (b) (d) 4. 4 (c) 6+1 A FAD = B FcD = с D 100 KN C D 1/3 T/6 В. A
