Question

Determine the force in each member of the truss.

Determine the force in each member of the truss and state if the members are in tension or compression (Figure 1) Part A Determine the force in the member AB of the truss, and state if the member is in tension or compression. Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression.

Answer 1

Answers

F_AB = - 8 kN

F_AC = - 1.45833333 kN

F_AF = 4.16666667 kN

F_BC = -3 kN

F_CD = -4.16666667 kN

F_CF = -3.125 kN

F_DE = -13.125 kN

F_DF = 5.2083333 kN

F_EF = 0

- ive sign shows compressive force

+ ive sign shows tensile force
