You will be using method of joints to solve for the external reactions and the forces in members $AB,AD,BC,$ and $BD.$ 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$.$

Assume the following values for question $1-4$:

Ay $=525lb$ up

$Cx=485lb$ to the left

$Cy=105lb$ down

$1.$ Using joint A $,$ determine the magnitude of the force in segment $AB.$ The units should be lbs$.$

$2.$ Using joint A $,$ determine the magnitude of the force in segment $AD.$ The units should be lbs$.$

$3.$ Using joint B $,$ determine the magnitude of the force in segment BC $.$ The units should be lbs$.$

$4.$ Using joint B$,$ determine the magnitude of the force in segment BD$.$ The units should be lbs

$5.$ For each of the following segments that you found in questions $1-4,$ is the segment in tension or compression.
