Hello, I have a physics question. Thanks in advance :) Question:  To escape a burning building, Arnold has to jump from a third-story window that is about 10.0 m above the ground. Arnold is worried about breaking his leg. The largest bone in Arnold’s leg is the femur, which has a minimum cross-sectional area of about 5.00 × 10−4 m. Arnold has a mass of 93.0 kg.   If Arnold lands on the ground with his legs stiff, and if his femur can compress only about 5.00 mm, what is the compressive stress on each femur?   If Arnold lands in deep snow, then his legs can move about 30.0 cm between the time they first hit the snow and the time he comes to a complete stop. What is the compressive stress on each femur?

700 KN 2.5 m A 2.5-m length of a steel pipe of 300-mm outer diameter and 15-mm wall thickness is used as a column to carry a 700-kN centric axial load. Knowing that E= 200 GPa and v=0.30, determine (a) the change in length of the pipe, (b) the change in its outer diameter, (c) the change in its wall thickness.

By how much will a 220 cm length of copper ( Y for Cu = 117,000 MPa) wire, 2.2 mm in diameter, elongate when a 4.8 kg mass is hung from its end?
