Solution to problem 2.4.47 from the collection of Kepe O.E.

2.4.47

It is necessary to determine the force modulus F at which the moment in embedment A is 300 Nm. It is known that the distributed load intensity q_max is equal to 400 N/m, and the dimensions of the segments AB, BD and BC are respectively 3 m, 1 m and 2.4 m.

To solve the problem, we use the formula for calculating the moment of force:

M = F * L, where

• M - moment of force
• F - force module
• L - distance from the point of application of force to the axis of rotation

In this case, the point of application of the force is point A, and the axis of rotation is point B.

The distributed load on segment AB is equal to:

q = q_max * (L₁ + L₂) / 2, where

• L₁ - length of segment AB
• L₂ - length of segment BC

Substituting known values, we get:

400 = 400 * (3 + 2,4) / 2

Thus, the length of the segment BC is equal to:

L₂ = 2 * 400 / 400 - 3 = 1.6 m

The distance from point A to the axis of rotation (point B) is equal to:

L = 1 + 1.6 = 2.6 m

And finally, the force module F:

F = M / L = 300 / 2,6 = 115,38 Н

Answer: 234.
