## How did you take the

How did you take the direction of force on the joint ?

## An easier to handle direction

An easier to handle direction of forces is by assuming all are tension (going away from joints). If your answer is positive then the assumption is correct. If the answer negative then the assumption is wrong, in means the correct direction is towards the joint (compression).
