An interesting question about perforated reinforcement

2016-01-28View Original

Thread Content

The reinforcement area for openings in a flat cover is half of the area that is weakened; the reinforcement for openings under external pressure is half of that required for internal pressure. Therefore, the reinforcement for openings in a flat cover when subjected to external pressure is 1/4 of what is needed for internal pressure. Interesting, right?

For a flat cover, the external pressure and internal pressure are the same, right?
