Four particles with masses m1 = 14 kg, m2 = 22 kg, m3 = 2 kg,and m4 = 32 kg sit on a very light (massless) metal sheet and are arranged as shown below.Find the moment of inertia of this system with the pivot at the following point.(Assume the rotation axis is parallel to the z direction,perpendicular to the plane of the drawing)
有四个质量为m1 = 14 kg, m2 = 22 kg, m3 = 2 kg,and m4 = 32 kg的粒子放在一个可以忽略质量的金属平面上,按照下图摆放.找到当P 为轴心(轴点)的时候的惯性和原点为轴点(轴心)的惯性.

题目是求转动惯量,I=∑ mi*ri^2=14*(9+0.25)+22*(16+25)+2*(9+1)+32*(2.25+2.25)=1195.5
