A simple span beam with a uniformly distributed dead load of 1.1 k/ft, including the self-weight, and concentrated dead loads of 3.4 kips and live loads of 6.0 kips at the third points of a 24-ft span, is to be designed with lateral supports at the third points and live load deflection limited to 1/360 of the span. Use the correct Cb, and be sure to check shear. Determine the least-weight Wshape to carry the loads.

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.
