in the sense that the section CB is a regulation tie rod therefore subject to two equal and opposite forces applied to the ends plus we have the force F applied in B (which is a hinge as the text says) which is unknown to determine. Since B is a hinge it will have two components

The loads on hinges C and B to be determined are written in the text.

the text says that B is a tie rod and you have to calculate the loads on C and B, interpreting that on CB there is a horizontal force HB. This is what I reasoned.

my doubt is that since the tie rod CB is a regulation one, only a horizontal force acts, therefore in B since it is a hinge there is the reaction Hb. Reasoning like this, however, I have 3 unknowns in 2 equations with the statics.

the only thing that doesn't make sense to me is the binding reaction in B since there is a hinge and since it is a regulation tie rod, shouldn't there be an unknown reaction in B?

Thank you very much for the solution.

thank you so much for your patience, i will try to do it again.

In conclusion, what are the reactions in A,B,C and D and the Force F worth?

Do the loads on hinges B and C not exert constraint reactions?

Thank you very much for your support but I wanted to ask you if my setting is correct or not.

I thought of solving it this way but I have 4 unknowns in 3 equations that cannot be solved.The problem is to find F which is unknown.

In the above solution the CB section with the constraint reactions is missing and then I thought that by exploding the structure the force F is divided into F/2 in the two parts.

Unfortunately there is nothing similar online and I find it very difficult to solve this exercise.

so what would the free scheme with the forces be? In the text it says to calculate the loads on the hinges A,B,C and on the pin D

The loads on hinges B and C are missing

These are the constraint reactions of the hinges

Is the identification of the forces at play correct? Could you guide me to the resolution.

this is how i thought to set it up

This is an exam assignment on machine construction and the professor told me that F can be obtained immediately, by making some assumptions. But I don't understand how?

The figure (attached) shows the arm of a lift in the particular position in which while the adjustment tie rod CB is horizontal, it also happens that the section of the lifting cable DE is horizontal. With the measurement dimensions and with the mass M = 500 kg to be lifted, the loads on the...
