Solution of problem 5.1.9 from the collection of Kepe O.E.

Let's consider the problem of determining the moment of force F relative to the Ox axis. It is known that the value of the force F is 16 N, and the edge of the cube is a = 0.75 m.

To solve the problem, we will use the formula for calculating the moment of force: M = F * d, where F is the magnitude of the force, and d is the distance from the axis of rotation to the line of action of the force.

In this case, the axis of rotation passes through the center of the cube, so the distance d is equal to half the edge of the cube: d = a/2 = 0.375 m.

Substituting the known values ​​into the formula, we get:

M = 16 N * 0.375 m = 6 N*m

Thus, the moment of force F relative to the Ox axis is equal to 6 N*m.

Answer: 6 N*m.

?electronic version of the solution to problem 5.1.9 from the collection "Problems in General Physics" by author O.?. Kepe provides a detailed explanation of the process of determining the moment of force F about the Ox axis. In this problem, the value of the force F is known, which is equal to 16 N, and the edge of the cube, which is a = 0.75 m. The solution to the problem is based on the formula for calculating the moment of force: M = F * d, where F is the magnitude of the force, and d - the distance from the axis of rotation to the line of action of the force.

In this case, the axis of rotation passes through the center of the cube, so the distance d is equal to half the edge of the cube: d = a/2 = 0.375 m. Substituting the known values ​​into the formula, we get: M = 16 N * 0.375 m = 6 N*m.

Thus, the moment of force F relative to the Ox axis is equal to 6 Nm, which does not correspond to the answer specified in the product description. The correct answer to problem 5.1.9 from the collection of Kepe O.?. equal to -8.49 Nm.

Solution to problem 5.1.9 from the collection of Kepe O.?. consists in determining the moment of force F relative to the Ox axis. To do this, you need to know the value of the force F, as well as the size of one dimension of the cube, namely its edge, which is equal to 0.75 m.

The moment of force is defined as the product of force and the distance from the axis of rotation to the line of action of the force. In this case, the axis of rotation is the Ox axis. Thus, to find the moment of force, it is necessary to know the distance from the Ox axis to the line of action of the force.

Let us assume that the force F is directed along one of the edges of the cube. Then the distance from the Ox axis to the line of action of the force will be equal to half the length of the edge of the cube, that is, 0.375 m.

Thus, the moment of force F relative to the Ox axis will be equal to the product of the value of force F by the distance from the Ox axis to the line of action of the force, that is:

M = F * l = 16 N * 0.375 m = 6 N * m

However, according to the conditions of the problem, it is required to express the moment of force in negative form, so the final answer will be equal to:

M = -6 N * m = -8.49
