Home exercise 1.4 Given a T-frame with a pinned support in $A$ and a simple roller bearing at $B$, permitting motion at $45^{?}$. A vertical force $P$ is acting at the tip in $D$. 1) Determine the reaction components. Represent the inclined reaction in $B$ by its horizontal and vertical components. (1p) 2) Determine and draw the distribution of internal forces $N,Q$ and $M$. (3p) 3) Isolate the joint $C$ and verify force and moment equilibrium. (1p)
