For a bronze alloy, the stress at which plastic deformation begins is 274 MPa and the modulus of elasticity is 112 GPa. (a) What is the maximum load that may be applied to a specimen having a cross-sectional area of 338 mm2 without plastic deformation? (b) If the original specimen length is 106 mm, what is the maximum length to which it may be stretched without causing plastic deformation?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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.
