1. Geometry of masses. Mass. Center and tensor of inertia
Determine the mass, the position of the center of gravity and the moment of inertia of a section of cylinder (figure 1 ).
In this particular case, it's simpler to use cylindrical coordinates. Here, the "Int" function is an inert function: the integral is not evaluated:
>M:≥Int(Int(Int(r*rho,z≥-L/2..+L/2),r≥0..R),theta≥-beta..beta);
