An idealised frame supports a load as shown in the figure. The horizontal component of the force transferred from the horizontal member PQ to the vertical member RS at P is \underline{\hspace{2cm} N (round off to one decimal place).} \includegraphics[width=0.35\linewidth]{image99.png}

A beam is subjected to a system of coplanar forces as shown in the figure. The magnitude of vertical reaction at Support P is \underline{\hspace{2cm} N (round off to one decimal place).} \includegraphics[width=0.75\linewidth]{image66.png}

The cross-section of a girder is shown in the figure (not to scale). The section is symmetric about a vertical axis (Y-Y). The moment of inertia of the section about the horizontal axis (X-X) passing through the centroid is \underline{\hspace{2cm} cm$^4$ (round off to nearest integer).} \includegraphics[width=0.25\linewidth]{image47.png}
