All members of the frame shown below have the same flexural rigidity EI and length L. If a moment M is applied at joint B, the rotation of the point is
-
-
ML 12EI -
ML 11EI -
ML 8EI -
ML 7EI
-
Correct Option: B
Stiffness of members,
| KBA = | L |
| KBC = | L |
| KBD = | L |
Rotational stiffness = Sum of stiffness of all member
| ⇒ K = | L |
| Rotation at B, θB = | = | |||
| k | 11EL |
