For the blue section shown below, determine the orientation of the principal centroidal axes in degrees and the principal centroidal moments of inertia in mm^4. The thickness of each rectangle is 4 mm. Use Mohr\'s Circle. (For theta_p, enter the value with the smallest magnitude.) theta_p = degree I_min = mm^4 I_max = mm^4

Solution

From the above givem data thepa and I can be calculated as ffollows

thetap = 56

Imax= 567 m^6

Imin = 68m^5
