Dear Matlab, My Professor showed us in class today how to use ode45 to solve a differential equation numerically. I would like to use it on my homework but I have a second order differential equation and the example I saw in class was only first order. Can ode45 be used for second order diffeqs? What do I need to do differently?

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.
