Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Ideal truss assumptions simplify analysis.
Step 1: Evaluate A.
Weights are usually neglected → false.
Step 2: Evaluate B.
Smooth pins assumed → true.
Step 3: Evaluate C.
Members are rigid (not flexible) → false.
Step 4: Evaluate D.
Loads applied only at joints → true.
Step 5: Final selection.
\[ B \text{ and } D \] Final Answer: \[ \boxed{B, D} \]
