2. A 2D truss as show below a. Determine if the truss is simple truss or not? b. Determine if there is any zero-force member? If a member is a zero-force member, it can be removed from the truss. c. Draw Free Body Diagram of the truss after removing all zero-force member d. Determine support reactions at \( E \) and \( F \) f. Determine internal force in members BD, CD, and CE. State each member is under tension or compression? Hint: for simple calculation, resolve the 130 lb external force at \( \mathrm{A} \) in \( \mathrm{x} \) and \( \mathrm{y} \) components.
