Cortical bone sample has 200 mm long, outside Dia. 50 mm and 40 mm diameter medullary cavity. It is fixed with 20 mm diameter metal prosthetic device and bone cement in it. The axial compressive load 1KN is applied. Calculate the following: a) Stresses and strains in longitudinal direction each component. b) An equivalent modulus with and without bone cement. Compare the two equivalent Moduli.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
