Solution of problem 2.3.4 from the collection of Kepe O.E.

2.3.4 Beam AB is subject to vertical forces F1 = 1 kN, F2 = 2 kN and F3 = 3 kN. Determine the reaction of support B in kN if the distances AC = CD = DE = 1 m, BE = 2 m. (Answer 1,2)

Given a beam AB, which is subject to vertical forces F1 = 1 kN, F2 = 2 kN and F3 = 3 kN. Distances AC, CD, DE are 1 meter and distance BE is 2 meters. It is necessary to determine the reaction of the support B in kilonewtons.

To solve the problem, it is necessary to use moment balancing. The sum of the moments of forces acting on the beam must be equal to zero.

The moment of force F1 is equal to F1 * AC, the moment of force F2 is equal to F2 * CD, and the moment of force F3 is equal to F3 * DE. The vertical reaction of the support B also acts on the beam. The moment of this force is equal to the reaction B multiplied by the distance BE.

Thus, the equation for balancing moments will be:

F1 * AC + F2 * CD + F3 * DE - В * BE = 0

Substituting the values, we get:

1 * 1 + 2 * 1 + 3 * 1 - B * 2 = 0

6 - 2B = 0

B = 3 kN

Thus, the reaction of support B is 3 kilonewtons.

Solution to problem 2.3.4 from the collection of Kepe O.?. consists in determining the reaction of support B on beam AB, which is acted upon by vertical forces F1 = 1 kN, F2 = 2 kN and F3 = 3 kN. Distances AC = CD = DE = 1 m, BE = 2 m.

To solve the problem, it is necessary to draw up equilibrium equations, taking into account that the sum of the moments of forces acting on the beam relative to any point must be equal to zero, and the sum of the vertical forces must be equal to zero.

Applying these laws, we can determine the reaction of support B. Having solved the equations, we get the answer 1.2 kN.
