Problem 1 For the frame loaded as shown, determine all the forces on members AD and ABC. Support at C is a roller. Hint: Please be careful in this problem: at point A, there are three elements connected at A: a pin A that is connected to ground (so, two support reactions due to that, say Ax and Ay), then, bar AD (two more reactions at A due to bar AD: call these as Ax_prime, and Ay_prime) and the bar AC (two more reactions at A due to bar AC: call these as Ax_doubleprime, Ay_doubleprime). So, you will need to draw a pin FBD at A showing all the six forces. 200 N 130 mm 400 mm 400 N C A, |B - 400 mm -400 mm

Problem 1
For the frame loaded as shown, determine all the forces on members AD
and ABC. Support at C is a roller. Hint: Please be careful in this problem: at point A, there are three
elements connected at A: a pin A that is connected to ground (so, two support reactions due to
that, say Ax and Ay), then, bar AD (two more reactions at A due to bar AD: call these as Ax_prime,
and Ay_prime) and the bar AC (two more reactions at A due to bar AC: call these as
Ax_doubleprime, Ay_doubleprime). So, you will need to draw a pin FBD at A showing all the six
forces.
