Final answer:
The force in member BE of a loaded truss can be found by using equilibrium analysis, including resolving forces into components and applying conditions of static equilibrium, to solve for unknown forces.
Step-by-step explanation:
The student has asked to determine the force in member BE of a loaded truss. In solving statically determinate trusses, we often use methods such as the 'method of joints' or the 'method of sections'. When analyzing the forces in a truss, forces are treated as vectors represented by arrows showing the direction and magnitude of the forces. The system is considered to be in static equilibrium when the net external force is zero, meaning that forces cancel each other out when added head-to-tail. In the case of tension forces like those mentioned in the provided strategies, we can employ equilibrium conditions and trigonometry to find the tensions in ropes or truss members.
For the scenario provided, it is imperative to analyze the structure as a whole, breaking it down into each component and considering the weight distribution, as well as external forces. After drawing a free-body diagram and setting up equilibrium conditions for forces and moments, the force in member BE can be calculated by solving the set of equations that result from the equilibrium conditions. This computation often involves resolving forces into their components and applying conditions that forces in any direction must sum to zero for the static case, and that the sum of torques about any point must also equal zero.
