Wally Wallington is a retired carpenter who believes that he found a way for ancient people to have built Stonehenge. In fact, he has been reconstructing Stonehenge on his own using only simple tools such as wooden levers, stones, sand, water, ropes, and old paint drums. On his own, he has erected concrete columns weighing approximately 20,000 lb. He says that his passion for moving heavy objects with modest equipment started when he was working as a carpenter and had to remove 1200-lb concrete blocks. One solution would have been to break the blocks into smaller pieces and then use wheelbarrows to remove the pieces. Wally thought of a better way. He used levers to move the blocks; he found that the process became very easy with practice. Think of how you might reproduce Wally’s original work. Assume he had some reasonably strong lengths of wood and a few old paint drums that he could fill with loose rock, sand, or water. Describe in detail how you might lift a 1200-lb block using a lever.Â
