When the tucurui dam was constructed in northern brazil, the lake that was created covered a large forest of valuable hardwood trees. it was found that even after 15 years underwater the trees were perfectly preserved and underwater logging was started. during the logging process a tree is selected, trimmed, and anchored with ropes to prevent it from shooting to the surface like a missile when cut. assume that a typical large tree can be approximated as a truncated cone with a base diameter of 8 ft , a top diameter of 2 ft , and a height of 100 ft . determine the resultant vertical force that the ropes must resist when the completely submerged tree is cut. the specific gravity of the wood is approximately 0.6.
