$.$ What is the total point load on point A that you will use in your calculations? State the

magnitude and direction. Discuss some of the assumptions you made.

$2.$ Think about other types of loads that this awning$/$frame may experience. Discuss these, but

do not include them in your calculations.

ANALYSIS

Member DC is a gas cylinder that helps to support member EB$.$ It is also able to change lengths which

helps the awning frame extend out from the camper and collapse into the camper for compact traveling.

$($Figure $2$ shows the fully extended frame$)$

$3.$ Select a gas spring that has an appropriate length and force for this application. You should

report the minimum and maximum length the gas spring needs to be as well as the force

required in the gas spring. Support this answer with all FBDs and work that led you to this

decision. Be sure to state any assumptions you make.

$4.$ Draw the shear and bending moment diagram for member EB$.$ Discuss what the results tell

you.

Hint: Even though members may be shown in Figure $2$ at an angle, the shear and bending

moment diagrams should still be drawn horizontal.

Member FC can be idealized as a two$-$force member, however, it actually consists of two members which

slide together via a bolt as shown in Figure $3.$ Member FG is made of aluminum and the bolt is made of

steel so you can look up the static friction coefficient between these two materials $($Search online for a

$$friction coefficient table$$ and site the source you used$).$ Use this to static friction coefficient to do the

following task:

$5.$ Determine the force that the steel bolt must exert on the aluminum member in order for the

members to not become disengaged. Support this answer with a FBD and any associated work.
