Product description
1. Calculate the mass of the D heterogeneous plate, given the limited lines, if the areal density at each point μ = μ (x, y)
1.10. D: x = 1, x = y2, μ = 4 - x - y
2. Calculate the static moment of a homogeneous plate the D, limited data lines, with respect to said axis, using polar coordinates.
2.10. D: x2 + y2 + 2ax ≤ 0, x2 + y2 + 2ay ≥ 0, y ≤ 0, Oy
3. Calculate the coordinates of the center of mass of a homogeneous body, occupying the area of the V, bounded by said surfaces.
3.10. V: 3z = √x2 + y2, x2 + y2 = 4, 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.
4.10. V: y = x2 + z2, y = 3, Oy
