Question

The degree of static indeterminacy of the beam shown below is

• A. 1
• B. 4
• C. 3
• D. 2

Answer 1

The correct option is C 3



$No.ofequilibriumequations=3\left[\begin{array}{c}\sum F_V=0\\ \sum F_B=0\\ \sum F_M=0\end{array}\right]$

$\therefore$ $D_s=No.ofexternalreactions-No.ofequilibriumequations$
= 6 - 3 = 3.
