This final reading is : Therefore, the cross section area of a thin wire with this diameter should be : Group of answer choices 4.70 mm, 15.02 mm2, 4.53 mm, 16.08 mm2 4.81 mm, 18.17 mm2 4.31 mm, 14.06 mm2

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
