Final answer:
The question involves calculating bending, compression, and tension of poles or composite panels in a physics context. Three-point bending test requirements are not directly answered, but the concepts of stress and strain related to physics are addressed.
Step-by-step explanation:
The information provided seems to pertain to problems about stresses and bending in materials, which is a concept found in physics. Specifically, this concerns the three-point bending test for composite panels used to ascertain the flexural properties of a material.
The dimension requirements and support span distance requirements are critical factors for conducting these tests appropriately. However, the question details a scenario analyzing the bending and compression of poles due to forces and tensions, which implies a more general physics problem involving equilibrium, stress, and strain.
In typical three-point bending tests, the dimensions of the test sample and the distance between the supports (span) are dictated by standards such as ISO 178 or ASTM D790. Manufacturers must select the correct span-to-depth ratio to prevent premature failure or improper loading. In the given scenario, we're looking at a series of physical evaluations such as calculating the bend of a pole due to tension applied by wires, the compression of the pole, and the tension of guy wires used to stabilize the pole.
These are complex questions that relate to static equilibrium, material properties like Young's modulus, geometry, and trigonometry
