24.9 mm 6.4 mm 12.4 mm 51 mm し76 x 51 x 6.4 6.4 mm 76 mmUsing Mohr's circle, determine, for the cross section of the rolled-steel angle shown in the figure, the orientation of the principal centroidal axes and the corresponding values of the moments of inertia. Given, I⎯⎯x I ¯ x = 0.162 × 106 mm4 and I⎯⎯y I ¯ y = 0.454 × 106 mm4.

The principal axes are obtained by rotating the xy axes through ° (Click to select)in the counterclockwise directionin the clockwise direction.(Round the final answer to one decimal place.)

The maximum moment of inertia is  × 106 mm4. (Round the final answer to three three decimal places.)

The minimum moment of inertia is  × 106 mm4. (Round the final answer to four decimal places.)
