Problem

The sketched $-$ two rigidly attached straight beams $-$ structure is fixed with one hinged and one roller support. The structure is loaded by planar forces and force couples, and a linearly changing distributed force.

$1.$Draw a scaled diagram of the structure!

$2.$Prepare a free$-$body diagram of the structure, mark the reaction components at the supports and calculate the reaction force system!

$3.$For the case $M_0=0$

$($a$)$ Determine the unknown reaction forces again by utilizing the equilibrium of three forces in drawing! Construct the magnitude of the reaction forces on a new scaled force diagram separately from the structural diagram!

$($b$)$ Compare the results of the force diagram with the earlier calculations $($from the equilibrium equations$)!$
