8. a cow femur is subject to a 500n load. assuming the mineral component has a young’s modulus of 17 gpa and collagen has a young’s modulus of 0.1 gpa, calculate the percentage of the load borne by the mineral phase of bone.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
