The femur, the long bone in the thigh, can be modeled as a tube of compact bone for most of its length. The cross-section area of the compact bone in the femur of a 70 kg person is 4.8 x 10-4 m2, a typical value.a. If this person supports his entire weight on one leg, what fraction of the tensile strength of the bone does this stress represent?b. By what fraction of its length does the femur shorten?

A current problem in the U.S. Air Force is the neck/shoulder fatigue experienced by pilots. To be able to fly missions at night, the pilots wear night vision goggles, which are attached to the front of the helmet. Unfortunately, these are heavy, causing a large downward torque of the head, which must be counteracted by the neck muscles, which then fatigue. To alleviate this problem, many pilots have started attaching random lead weights to the back of the helmet. Find the appropriate weight that would best balance the head and minimize neck fatigue – You must show your free body diagram. Assumptions: a) center of gravity of goggles is 20 cm in front of neck pivot point, b) load of goggles1.0 kg mass, c) center of gravity of lead weight is 10 cm behind neck pivot point, d) load of bare helmet 3 kg mass, e) center of gravity of helmet is 2 cm in front of neck pivot, f) load of head 4.0 kg mass, and g) center of gravity of head is right at neck pivot point.

A ceramic with KIc = 4 MPa m1/2 contains pores with radius a = 5 µm due to incomplete sintering. These pores lead to a decrease in the failure stress of the material in both tension and compression. One in every ten grainboundary junctions contains a void; the grain size of the ceramic is 50 µm. The ceramic fails in compression when the length ℓ of each crack generated at the voids equals one-half of the spacing between the voids. (a) Determine the compression strength of the ceramic, using the equation from Sammis and Ashby. (b) Determine the tensile strength of the ceramic, assuming flaws with size a.
