Pregunta: Suppose that P1=6kN,P2=8kN, and P3=12kN. (Figure 1)Determine the force in member BC of the bridge truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension. Part B Determine the force in member HC of the bridge truss. Express your answer

Suppose that $P_1=6\mathrm{kN},P_2=8\mathrm{kN}$, and $P_3=12\mathrm{kN}$. (Figure 1) Determine the force in member $BC$ of the bridge truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension. Part B Determine the force in member $HC$ of the bridge truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension. Determine the force in member $HG$ of the bridge truss. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension.
