Extracted text: c) Consider the situation where P = 4 kN, and Q and R are both non-zero forces acting in the direction shown in the figure. The forces in the members connected to the support at A are indicated in the table below. Calculate the forces in members LK, LC and BC. For all the indicated truss members, state if the members are in tension, compression, or if they are zero-force members. The nature of the members are negatively marked; points will be deducted for every incorrectly selected option. Member Force Nature of force AL 17.29 kN АВ 10.8 kN LK kN LC kN ВС kN
