2.4.48 Determining the length of an aircraft section

It is required to find the length of section BC at which the moment in embedment A is 180 N m, if the size of AC is 2 meters and the intensity of the distributed load q is 30 N/m.

Answer: 2.0 meters.

To solve this problem you need to use the formula:

M = q * L^2 / 8, where

• M - moment at closing A
• q - distributed load intensity
• L - length of the aircraft section

Substituting the known values ​​and solving the equation for L, we get:

L = √(8 * M / q)

Substituting specific values, we get:

L = √(8 * 180 / 30) = 2.0 meters.

Thus, the length of the section BC is 2.0 meters.

Solution to problem 2.4.48 from the collection of Kepe O.?. consists in determining the length of section BC at which the moment in embedment A is equal to 180 N m. The size of the AC is known, equal to 2 m, and the intensity of the distributed load q, equal to 30 N/m. It is necessary to find the length of the section BC.

To solve the problem, it is necessary to use a formula to determine the deflection moment of a beam under a distributed load: M = qL^2/8, where M is the deflection moment, q is the intensity of the distributed load, L is the length of the beam section.

Substituting the known values, we get the equation 180 = 30L^2/8. Having solved it, we find the length of the section BC equal to 2 meters.

Thus, the solution to problem 2.4.48 from the collection of Kepe O.?. consists in determining the length of section BC at which the moment in embedment A is equal to 180 N m, and it is equal to 2 meters.
