Problem 2 of 2: The space truss is loaded with the vertical force 30 kN. For all elements, E = 1.8∙1011 Pa, A = 0.001 m2. Determine the nodal solution and element solution (stresses), given the nodal coordinates (in meters):1:(2,3,0), 2:(2,0,2), 3:(4,0,0), 4:(2,0,0), 5:(0,0,0)

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
