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 14 ft, a top diameter of 10.0 ft, and a height of 89 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 .
