9. [-/1 Points] DETAILS OSCOLPHYS2016 5.3.P.032. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER TV broadcast antennas are the tallest artificial structures on Earth. In 1987, a 66.0 kg physicist placed himself and 400 kg of equipment at the top of one 610 m high antenna to perform gravity experiments. By how much (in mm) was the antenna compressed, if we consider it to be equivalent to a steel cylinder 0.145 m in radius? (Assume a Young's modulus of 20 x 1010 pa.) mm Additional Materials Reading
