Solution to problem 6.3.15 from the collection of Kepe O.E.

6.3.15 It is necessary to find the coordinate zc of the center of gravity of a homogeneous body formed from two cylinders with radius R = 2r and height H = 0.5 m, if the height of the first cylinder is H1 = 2H.

Answer: 0.5

To solve the problem, you need to find the volume and mass of the body, and then use the center of gravity formula to determine the zc coordinate. The volume of one cylinder is equal to V1 = πR^2H, and the mass m1 = ρV1, where ρ is the density of the material. The volume of the second cylinder is V2 = πr^2H, and the mass m2 = ρV2. The total volume of the body is V = V1 + V2, and the total mass m = m1 + m2. The coordinate zc of the center of gravity is equal to zc = (V1zc1 + V2zc2)/V, where zc1 and zc2 are the coordinates of the centers of gravity of each cylinder. After substituting the numerical values, we get zc = 0.5 m.

Problem 6.3.15 from the collection of Kepe O.?. consists in determining the coordinate zc of the center of gravity of a homogeneous body consisting of two cylinders. One cylinder has a height H1 = 2H, a radius R = 2r, and the other cylinder has the same dimensions, but a height H = 0.5 m. To solve the problem, it is necessary to use a formula for determining the coordinates of the center of gravity of many bodies, which looks like this:

zc = (m1 * z1 + m2 * z2) / (m1 + m2)

where zc is the coordinate of the center of gravity, m1 and m2 are the masses of the bodies, z1 and z2 are the coordinates of the centers of gravity of each of the bodies.

To calculate the mass of each cylinder, you must use the formula to determine the volume of a cylinder:

V = π * R^2 * H

where V is the volume of the cylinder, R is the radius of the cylinder, H is the height of the cylinder.

After calculating the masses of each cylinder, the coordinates of the centers of gravity of each of them can be determined. For a cylinder of height H they will be at height H/2, and for a cylinder with height 2H they will be at height H.

By substituting the obtained values ​​into the formula for determining the coordinates of the center of gravity, you can find the desired answer. In this problem the answer is 0.5 m.
