Direction: A rigid beam is hinged at one end and supported on linear elastic springs (both having a stiffness of ‘k’) at points ‘1’ and ‘2’ and an inclined load acts at ‘2’, as shown.
-
Which of the following options represents the deflections δ1 and δ2 at points ‘1’ and ‘2’?
-
-
δ1 = 2 2P and δ2 = 4 2P 5 k 5 k -
δ1 = 2 P and δ2 = 4 P 5 k 5 k -
δ1 = 2 P and δ2 = 4 P 5 √2k 5 √2k -
δ1 = 2 √2P and δ2 = 4 √2P 5 k 5 k
-
Correct Option: B
Taking moment about hinge.
MH = 0
kδ1 + kδ2.2L = p × 2L
∴ kδ1 + 2kδ2 = 2P
From the figure,
⇒ δ2 = 2 × δ1
(since the distance is l for both)
∴ δ1 = | , δ2 | |||
5k | 5k |
