• A. $\begin{array}{cccc}3& 1& 2& 4\end{array}$
• B. $\begin{array}{cccc}3& 4& 2& 1\end{array}$
• C. $\begin{array}{cccc}2& 1& 4& 3\end{array}$
• D. $\begin{array}{cccc}2& 4& 3& 1\end{array}$

Answer 1

The correct option is A $\begin{array}{cccc}3& 1& 2& 4\end{array}$

$\frac{dV}{dx}=w$

Slope of SFD = Load intensity.

P. Figure represents some slope of SFD in the whole span it means UDL in the whole span, hence fig(3)

Q. Fig. shows slope of SFD in the end span and zero slope in the middle span so it means UDL in the end span and no loading or point load in the middle span hence fig(1)

R. Figure shows zero slope of SFD in the whole span. It means UDL is not acting in the whole span, only point load acts, further shear force change sign in the middle span it means some point load is acting in middle span hence fig(2) S.Fig(4)
