Final Answer:
BE: Tension force of 4 kN
CE: Compression force of 3 kN
Step-by-step explanation:
The determination of forces in members BE and CE involves analyzing the truss under load. Applying the method of joints, we ascertain that member BE experiences tension with a force of 4 kN. This tensile force is due to the external loads applied at joint E. Concurrently, member CE undergoes compression, sustaining a force of 3 kN.
This compression results from the equilibrium of forces at joint C under the applied loads and reactions. The load distribution and truss geometry necessitate these specific forces in BE and CE to maintain structural stability.
The force analysis relies on the equilibrium of joints and the principles of statics. Member BE endures tension because it's subject to pulling forces along its length, while member CE, due to its positioning and load distribution, is compressed, pushing against its structure.
This determination aids in understanding the load-bearing capacity and stress distribution within the truss system, crucial for ensuring structural integrity and safety.
