Example - Analysis of Trusses using the Method of
Joints (continued)

Finally construct a FBD of the members at joint B and express the equations of equilibrium. Again assume the forces in all truss members whose forces are unknown to be in tension. Σ Fx = 0 gives - 1600 (√2) (1/√2) + 800 (√2) (1/√2) + FBD = 0 So FBD = 800 N (in tension) Click here for the same example using the method of sections. |
