Question

What is the Kinematic Indeterminacy for the given frame without axial deformation?

• A. 8
• B. 20
• C. 12
• D. 18

Hint:

To calculate the kinematic indeterminacy of a frame, focus on the number of joints and reactions to apply the correct formula.

Answer 1

The Correct Option is B

The degree of kinematic indeterminacy (DOF) for a frame without axial deformation can be determined using the following formula: \[ DOF = 3n - 2r \] Where: - \( n \) is the number of joints, - \( r \) is the number of reactions. Using this formula for the given frame, the kinematic indeterminacy is 20. Thus, the correct answer is 20.
