The shaft of a long bone consists of two layers of bone; extemal with E=10GPa, and intenal E=1GPA, their diameters are 35mm and 25mm, respectively. If a compressive force is applied on the system F=1200N÷last two numbers of your ID a) how much is the reduction in length given the length is=0.32m. b) if the shaft is replaced with a hollow circular metal element of the same length (L=0.32m), and with internal diameter =35mm, E-8OGPA, how much should its external diameter be to give the same deformation?

5. The shaft of a long bone consists of two layers of bone; extemal with
E=10GPA, and internal E=1GPA, their diameters are 35mm and 25mm,
respectively. If a compressive force is applied on the system F=1200N+last
two mumbers of your ID
a) how much is the reduction in length given the length is=0.32m.
b) if the shaft is replaced with a hollow circular metal element of the same
length (L-0.32m), and with internal diameter =35mm, E-8OGPA, how
much should its external diameter be to give the same deformation?
