A cantilever beam OP is connected to another beam PQ with a pin joint as shown in the figure. A load of 10 kN is applied at the mid-point of PQ.
The magnitude of bending moment (in kN–m) at fixed end O is ________
-
- 2.5
- 5
- 10
- 25
Correct Option: C
P-being internal hinge
∑MP = 0 ...(1)
Condition ‘PQ’, reaction at Q i.e. RQ = 10 kN
Now from (1), ∑MP = 0
M0 – RQ × 1 + RC × 0.5 = 0
⇒ M0 = 10kN
