Part A Consider the truss shown in (Figure 1). Suppose that $F_1 = 4.5$ kN and $F_2 = 6.5$ kN. After the truss is sectioned use a single equation of equilibrium for the calculation of each of the required forces. Determine the force in member BC. State if this member is in tension or compression. 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. $F_{BC} =$ Value Units Submit Request Answer Part B Determine the force in member HC. State if this member is in tension or compression. 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. $F_{HC} =$ Value Units Submit Request Answer Part C Determine the force in member HG. State if this member is in tension or compression. Express your answer to three significant figures and include the appropriate units.
