A pin jointed frame (Figure 2) support a gravity load of 5k at C. An impulse cause the frame to vibrate freely in vertical direction with a velocity of 0.2 ft/s. Calculate: 1. Static force corresponding to peak dynamic displacement. 2. Time required to complete 10 cycles during free vibration Diameter of both members is 9/8 in Take E= 29,000 ksi

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.
