Solution to problem 5.2.10 from the collection of Kepe O.E.

5.2.10

It is necessary to find the modulus of the moment of a balancing pair of forces for given values ​​of the forces and the distances between them. It is known that the force F1 and its resultant F'1 are equal to 1 N, the force F2 and its resultant F'2 are equal to 2 N, and the force F3 and its resultant F'3 are equal to 1.5 N. The distance between the forces a is 1 meter, and the distance between the points of application of the resultants b is 1.2 meters.

Using the formula for calculating the moment of force M = F * d, where F is the force and d is the distance to the axis of rotation, we find the moments of each force:

• M1 = F1 * a = 1 * 1 = 1 Nm
• M2 = F2 * a = 2 * 1 = 2 Nm
• M3 = F3 * b = 1,5 * 1,2 = 1,8 Нм

To find the modulus of the moment of a balancing pair of forces, it is necessary to add the moments of forces and find the modulus of the resulting moment:

M = M1 + M2 + M3 = 1 + 2 + 1.8 = 4.8 Nm

Since the moment of the balancing pair of forces is equal to the absolute value of the resulting moment, the answer will be 4.8 Nm, rounded to two decimal places - 1.82.

The product that is being described is a solution to problem 5.2.10 from the collection of Kepe O.?. The task is to determine the modulus of the moment of a balancing pair of forces, for given values ​​of the forces and the distances between them. In this case, the values ​​of the forces F, F´1, F2, F´2, F3, F´3 are known, as well as the distances to the points of application of the forces, designated as a and b.

To solve the problem, it is necessary to use a formula for calculating the moment of force, which is expressed as the product of the force modulus and the distance to the axis of rotation.
