Problem 14.6.3 from the collection of Kepe O.?. consists in determining the moment of the resultant of all forces applied to a material point with a mass of 1 kg, moving according to the law x = 2t, y = t3, z = t4, relative to the Ox axis at time t = 1 s.

To solve this problem, you need to use the formula to find the moment of force about a given axis. In this case, you need to project all the forces applied to the point onto the Ox axis, then multiply each force by its arm (the distance from the axis to the line of action of the force), and add the resulting products.

Since the applied forces are not explicitly indicated in the problem, you need to use well-known formulas to calculate the force according to the law of motion. To do this, you need to find the derivatives of the coordinate functions with respect to time and substitute them into the formula for calculating the force. Then it is necessary to project the resulting force onto the Ox axis and find its shoulder.

After this, you can calculate the moment of the resultant of all forces relative to the Ox axis at the time t = 1 s, which is equal to 6.
