Question
How do you find the finding the theta for the components of Ab?
the equations I have found to solve the problem is...
Ay-FABSin(theta)=0 and -FABCos(theta)+Ax-FAG=0
because Ay is shown in tension and Fab and FAG Is assumed to be in compression.
round your answers to three decimal places and state if the member is in compression or tension (if the number you find for a member negative the the direction we assumed is wrong)
