The manufacturing company as well manufactures electric insulators. If insulators break when in use, a short circuit is likely to take place. To test the strength of insulators, destructive testing in high powered labs iscarried out to find out how much force is needed to break the insulators. Force is measured by observing how many pounds should be applied to insulator before it breaks. The strengths of 30 insulators are as follows:
