An Irish man and an English man were sitting in a pub discussing matters of the world. Well, one thing led to
another, and soon the two men were yelling at each other. Of course, each man thought he was better than
the other. The bartender was tired of listening to the men quarrel, and told them that they should have a
contest. Since they were both good at loudly proclaiming their righteousness, they decided to have a yelling
contest. Each man was to yell at the top of his lungs into a noise level meter held by the bartender. They were
to yell from a distance of 20 paces. The Irish man was so confident that he would win the contest, he told the
English man to stand 8 pace closer. Here are the noise levels recorded by the bartender. Irish man = 84.0 dBA

An insurance inspector notified Safety Manager Sam that his plant needs to install fall protection at the tanker
unloading dock. (Truck drivers must climb their trucks to open hatches and make connections.) Plant Manager
Pete (a mechanical engineer by training) decides to design and build the fall protection himself. Sam is

man (some truck drivers don’t get much exercise) after dropping 6 ft vertically. Sam also says he wants Pete to
build in a safety factor of 3, (to allow for REALLY BIG guys and other potential problems). Pete has the fall
protection installed, and they are going to test it by dropping a 900 lb weight a vertical distance of 6 feet. The
