What is the general guideline for the ratio of rib depth to wall thickness?

Understand the Problem

The question is asking about the standard ratio for rib depth relative to wall thickness. This is an important consideration in engineering design to ensure structural integrity and prevent issues like cracking or deformation. We need to determine the generally recommended ratio from the given options.

More Information

The ideal rib height should be 2.5 to 3 times the nominal wall thickness, according to the blog post 'The Cardinal Rules of Designing Injection Molded Plastic Parts'.

Tips

Some sources say that rib root thickness should not be more than 25% greater than the wall thickness, while others suggest that the rib depth should not be more than 5 times the rib thickness. It is important to double check all values.
