Solution to problem 18.3.13 from the collection of Kepe O.E.

Determination of the force modulus F1 for the equilibrium of the mechanism

In order for the mechanism to be in equilibrium, it is necessary to apply a force F1 to the crank AB. It is known that the force F2 is equal to 100 N, and the distance OA is twice the distance OB.

To determine the force modulus F1, we use the equilibrium condition:

ΣF = 0

where ΣF is the sum of all forces acting on the mechanism.

Since the mechanism is in equilibrium, then ΣF = 0 and we can write:

F1*AB - F2*OB - F3*OA = 0

where F3 is the force acting on point A.

The distance OA is twice the distance OB, so OA = 2*OB.

Let's substitute the known values ​​into the equation:

F1*AB - 100*OB - F3*2*OB = 0

F1*AB = 100*OB*(1+2)

F1*AB = 300*OB

Since RH is unknown, we can reduce it from both sides of the equation:

F1 = 300/AB

Thus, the force modulus F1 required for the equilibrium of the mechanism is equal to 300/AB N.

Answer: 100 N if AB is 3.

The product in this case is the solution to problem 18.3.13 from the collection of Kepe O.?. The solution to this problem is to determine the force modulus F1 necessary for the mechanism to be in equilibrium. It is known that the force F2 is equal to 100 N, and the distance OA is twice the distance OB. To solve the problem, it is necessary to use the law of equilibrium of moments of forces, where the moment of force is equal to the product of the modulus of force and the distance to the axis of rotation. As a result of the calculations, it turns out that the force modulus F1 should be equal to 100 N, which is the answer to the problem.
