AI Thread Summary
The discussion clarifies that when calculating the combined vector at a point, only the linear forces should be considered, as torque does not affect the resultant force at that specific point. The term "combined vector" refers to the net or resultant force, which is the sum of all forces acting at that location. Torque is calculated separately and does not influence the resultant force since the length is zero at that point. When moments are calculated relative to any point, they can be added to the forces. The conclusion confirms that the resultant force remains unchanged by the moment in this scenario.

What do you mean by "combined vector"? Do you want to calculate the sum of all forces (I assume they are forces) at that point?
 
I mean "net force" or "resultant force"
 
In that case, the quantity would just as you wrote be given by the linear forces. Torque is given by length times force, and length would be equal to zero for the point you've shown on your picture.
 
So yes, the resultant force remains exactly what you wrote, and the moment does not play a role in it.

Whenever you will calculate a moment relative to any point, you would simply add the moment to it.
 
Thank you! :smile: wasn't sure.
 

Thread 'Family of lines that are at a distance of 5 from the origin'

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...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
