Q25
Number of unknown internal forces in each member of a rigid jointed plane frame is
A.
1
B.
2
C.
3
AnswerD.
6
Answer: Option C
Solution
Answer: Option C
Solution:
The correct answer is Option C: 3. Here's why:
In a rigid jointed plane frame, each member is subjected to three internal forces:
* Axial Force: The force acting along the longitudinal axis of the member (tension or compression).
* Shear Force: The force acting perpendicular to the longitudinal axis of the member.
* Bending Moment: The internal moment that causes bending in the member.
Therefore, there are three unknown internal forces in each member of a rigid jointed plane frame.
