For the frame shown in the figure (not to scale), all members (AB, BC, CD, GB, and CH) have the same length, L, and flexural rigidity, EI. The joints at B and C are rigid joints, and the supports A and D are fixed supports. Beams GB and CH carry uniformly distributed loads of w per unit length. The magnitude of the moment reaction at A is \(\frac{wL^2}{k}\). What is the value of k (in integer)? \includegraphics[width=0.5\linewidth]{image77.png}

In the frame shown in the figure (not to scale), all four members (AB, BC, CD, and AD) have the same length and same constant flexural rigidity. All the joints A, B, C, and D are rigid joints. The midpoints of AB, BC, CD, and AD, are denoted by E, F, G, and H, respectively. The frame is in unstable equilibrium under the shown forces of magnitude \( P \) acting at E and G. Which of the following statements is/are TRUE? \includegraphics[width=0.5\linewidth]{image6.png}

An idealised bridge truss is shown in the figure. The force in Member U2L3 is \underline{\hspace{2cm} kN (round off to one decimal place).} \includegraphics[width=0.5\linewidth]{image95.png}

Consider the pin-jointed truss shown (not to scale). All members have the same axial rigidity, $AE$. Members $QR,\;RS,\;ST$ have the same length $L$. Angles $QBT,\;RCT,\;SDT$ are $90^\circ$ and angles $BQT,\;CRT,\;DST$ are $30^\circ$. A vertical load $P$ acts at joint $T$. If the vertical deflection of joint $T$ is $ \displaystyle \Delta_T=k\,\frac{PL}{AE}$, what is the value of $k$? \includegraphics[width=0.35\linewidth]{image88.png}
