Abrass alloy is known to have a yield strength of 240 mpa (35,000 psi), a tensile strength of 310 mpa (45,000 psi), and anelastic modulus of 110 gpa (16.0 x 106 psi). a cylindrical specimen of this alloy 15.2 mm (0.60 in) in diameter and 380 mm(15.0 in) long is stressed in tension and found to elongate 19 mm (0.075 on the basis of the information given, is itpossible to compute the magnitude of the load necessary to produce this change in length? if so, calculate the load; if not, explain why.

On a average work day more than work place firs are reorted

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.
