Final answer:
Examples provided relate to physical problems involving tension, forces, and material deformations, but do not directly answer the query about the maximum distance for cable support in suspended ceilings, which relies on NEC guidelines.
Step-by-step explanation:
The original question pertained to wiring NM and NMC cable supports for suspended ceiling luminaires, but the provided examples do not directly answer this query. Instead, they provide data on physical scenarios involving tension and forces in different contexts, such as a scaffold being supported by cables, and the effects of forces on a wire suspended from a pole. To address the question of maximum distance between points of support for wiring NM and NMC cable to suspended ceiling luminaires, we must refer to the National Electrical Code (NEC). However, this specific distance is not provided in the examples. Generally, the NEC stipulates that cables must be supported at least every 4.5 feet and within 12 inches from every box, cabinet, fitting, or other cable terminations.
Example 35 deals with calculating the tension in cables supporting a scaffold with known masses and distances from support points. This example uses principles of statics and mechanics.
Example 40 requires the calculation of how much a pole is bent and compressed due to the tension in supporting wires. This problem is about the deformation of materials under stress and also applies principles of physics and engineering.
