You are floating in a canoe down the wisconsin river moving with the current. assume that the flow is steady. (a) because the flow rate is steady, you do not accelerate as you float down the river.(b) because the river changes width and depth along its path, you accelerate as you float down the river.(c) you are continuously accelerating since the river is flowing downhill.(d) you will accelerate only if the flow becomes unsteady.

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.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
