Statics (smooth pin reaction + tension)

AI Thread Summary
In the discussion on statics involving smooth pin reactions and tension, the main focus is on determining the tensions in a system with different angles. The user questions whether tensions A and B can be the same due to their different angles, despite the principle that tension is constant over a smooth pulley. They express difficulty in solving for the tension in segment ADB and propose a relationship involving the sine of angles and forces to find the tension. The reaction at the pin is also noted as the sum of horizontal components. The conversation emphasizes the complexities of analyzing tension in a multi-segment cable system.

Homework Equations


\sum F_{x} = 0
\sum F_{y} = 0
\sum M = 0

The Attempt at a Solution


See figure (written in my writing).

Are the tensions A and B suppose to be the same? I imagine not because they are at different angles so they have different magnitudes but at the same time tension should be constant over the smooth pulley.

I'm having trouble solving the tension in ADB.

Any ideas?

In a single cable different segments must have the tension.
So
T*sinθ1*x1 + Τ*sinθ2*x2 = F*x3.
Now solve for T.
The reaction on the pin is ΣTx.
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
