Second Moments of Area- Exercise 2

A bolt system is represented by the distributed area shown below. Determine the

  1. Polar moment of inertia of each bolt cross-sectional area about its own centroidal z axis, J1, J2, J3
  2. Polar moment of inertia of the bolt system about the centroidal z axis of the bolt pattern, J0
  3. Polar radius of gyration r0 for the bolt system.

Round up your answers to three decimal places. You can submit one answer at a time by leaving the remaining answer fields blank or you can submit all answers together.

J1 = cm4    J2 = cm4     J3 = cm4

J0 = cm4     r0 =  cm
