The Correct Option is B
Solution and Explanation
Step 1: Identify the supports.
A propped cantilever consists of:
- One fixed support (3 reaction components)
- One roller support (1 reaction component)
Hence, the total number of reaction components is
\[
r=3+1=4.
\]
Step 2: Determine the degree of static indeterminacy. For a plane structure, \[ \text{Degree of Static Indeterminacy} =r-3. \] Therefore, \[ =4-3=1. \] Hence, \[ \boxed{1} \] is the correct answer.
Step 2: Determine the degree of static indeterminacy. For a plane structure, \[ \text{Degree of Static Indeterminacy} =r-3. \] Therefore, \[ =4-3=1. \] Hence, \[ \boxed{1} \] is the correct answer.
