When using Method of Joints, which node(s) could your analysis begin at to determine the forces in each member of the truss shown? Assume the reaction forces are all known.  

When using Method of Joints, which node would you analyse to determine the internal forces in members AB & BC of the truss shown?

In the truss system below, with the loading as shown, member BC;

Classify the following trusses as either unstable (U), determinate (D), or indeterminate (I).

(a) 

(b)

(c)

The truss shown has a horizontal load of P= 38.5 kN applied at joint B.  

Using the Method of Joints, calculate the force in member BC (in kN). Indicate whether the member is in tension or compression by using the '-' for compression and no sign for tension. 

Do NOT include any units.

Give your answer to 1 decimal place.
