1. Calculate the mass of the D heterogeneous plate, given the limited lines, if the areal density at each point μ = μ (x, y)
1.17. D: y = x2 - 1, y = 1, μ = 3x2 + 2y2 + 1
2. Calculate the static moment of a homogeneous plate the D, limited data lines, with respect to said axis, using polar coordinates.
2.17. D: x2 + y2 - 2ay = 0, x2 + y2 - ay = 0, x ≤ 0, Ox
3. Calculate the coordinates of the center of mass of a homogeneous body, occupying the area of the V, bounded by said surfaces.
3.17. V: z = 3 (x2 + y2), x2 + y2 = 9, z = 0
4. Calculate the moment of inertia with respect to said homogeneous body axes, occupying the area of the V, the limited data surfaces. body density δ taken equal to 1.
4.17. V: x2 = y2 + z2, x = 2, Ox
