You will first need to find the external forces. Then,

using the given values, you will find the forces in members $AB,AD,BC,$ and BD$.$ Use

the following information:

The truss members are shown in blue, and the applied forces are shown by the

black arrows.

The members are connected by a smooth pin at the joints shown in red.

The orange dashed lines are used to show dimensions.

There is a pin support at C$,$ and a rocker support at A$.$ Can you show me how to do this?

$1.$ Please draw the all FBDs needed to be able to solve for the external reactions and the forces members $AB,AD,BC,$ and $BD.$

$2.$ Determine the magnitude of the vertical force at $A(Ay).$ The units should be in Ibs.

$3.$ Determine the magnitude of the horizontal force at $C(Cx).$ The units should be in lbs$.$

$4.$ Determine the magnitude of the vertical force at C $($Cy$).$ The units should be in Ibs.

$5.$ For the external reactions that you found in questions $2-4,$ which direction does the force act
