When we make graphs, we usually plot the independent variable (the thing that we are changing) on the X axis and the dependent variable (the thing that responds to that change) on the Y axis. Typically for stress strain curves, stress is plotted on the Y axis and strain is plotted on the X axis. This makes sense for engineers as they often test materials by applying particular strains (length changes) and determine how much stress results. But as biologists, we often want to do the reverse, apply different stresses and see what the resulting strain is. Why are stress strain curves somewhat confusing when we think about them this way

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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
