In a Free Body Diagram, drawing arrows (to represent internal forces in trusses) away from the joints, indicates that the forces are in

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= 8.8 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.

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

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.  

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)

Which of the following statements is true regarding two-force members in equilibrium?

Identify the number of reactions on the member in each case.

How many equilibrium equations need to satisfied in order for a 2D system to be in equilibrium?
