Consider the Baltimore bridge truss shown in (Figure 1). Suppose that $P_1=1.5\mathrm{kN},P_2=5.5\mathrm{kN}$, and $P_3=3\mathrm{kN}$. Determine the force in member $EF$ and state if the member is in tension or compression. Part B Determine the force in member $EP$ and state if the member is in tension or compression. Part C Determine the force in member $KL$ and state if the member is in tension or compression. Indicate all zero-force members. Check all that apply. $BN$ CN $\mathrm{CO}$ DO EF $EL$ $EO$ EP GJ GP HJ $KL$ $LM$ none
