Using the method of joints, determine the forces on each of the members of the truss shown below. Assume the

weight of the members is negligible and the members are rigid.

Note that a pin connection exists on the lower left, while a roller connection exists on the lower right.

All unknown forces should be solved by your code. Do not solve for some of the forces by hand.

Here are a few forces to test whether you analyzed the system correctly:

Force AD $=$ Force BD $=$ Force CD $=4\mathrm{.}0981{10}^{3}N($tension$)$
