The analysis below is to be completed using the simplified model in Figure $2.$ For simplicity assume that the roof is pinned at point A $($see Figure $2).$ Figure $2$ also shows additional dimensions of the roof. The roof is $3$ m in length between points A and C $($labelled as length $"$a$").$ The cable force, FB$,$ acts at point B$,$ which is located at distance $"$c$"$ from point C$.$

The roof has a load from the self$-$weight of the structure, T$,$ that acts at point D$,$ which is located at distance $"$b$"$ from point A$.$ Snow can accumulate on the roof to a thickness of $0\mathrm{.}25$ m$,$ resulting in a uniformly distributed load $($UDL$),$ w$,$ applied between points A and C$.$ The snow has a density of $950$ kg$/$m$3.$

Note: mass of snow $=$ density of snow $*$ thickness of snow $*$ width of roof section

In your tutorial group complete the following and have the TA mark your work during the tutorial and record your work on onQ. Apply a sign convention that forces acting up and to the right are positive and clockwise moments are positive. Complete your calculations for a $1$ m width section of the roof.

Calculate the UDL, w$,$ with units of kN$/$m and enter it in the space below. Use $3$ significant figures.

Draw the free body diagram for the structure.

Develop equations for the reactions at A and the force in the cable, FB$,$ that work for any value of w$,$ T$,$ and angle,

$.$

Get the TA to check your work.

Complete the remaining tutorial questions on your own, enter your answers into onQ, and upload your calculations. For the remaining questions assume the canopy angle,

$,$ is zero degrees and the distance b is $1$ m$.$
