F, KN F, KN 2 60 60 60 3 Determine: The magnitude and direction of the reactions at 3 while force at joint 1 is 58 kN and the force at joint 2 is 52 kN. (Use the attachment tool to show me the working out and explain if the force is tension or compression). Make sure you write the negative sign if the answer is negative as that would be picked up from the system
