AI Thread Summary
Understanding tension in physics involves analyzing forces acting on objects, such as a picture hanging from two strings. The tension in each string can vary based on their angles and the weight of the object. In the provided example, the tension in string two can be determined by resolving the forces in both the x and y directions. The calculations for T1x and T1y help establish a relationship between the tensions and the weight of the picture. Properly applying these principles will clarify how to solve tension-related problems effectively.

I have having difficulty with tensions. Can someone give a good explanation of how they work and what are some rules to solve the problems I have for homework.

Here is one example of a problem:

A picture hangs on the wall suspended by two strings as seen in the figure 6-20(see below for a written explanation). The tension in string one is 1.7N. (a) is the tension in string 2 greater than, less than or equal to 1.7N (explain) (b)verify your answer by calculating the tension on in string 2 (c) what is the weight of the picture?

In the example there is a pictrue hanging in the middle of two strings, one string string one in 65degrees above the -X axis and string 2 is 32degrees above the X axis.

Here is what I have done:

T1x = 1.7(-cos115degrees)
T1y = 1.7(sin115 degrees)
and that is it...HELP!

sorry about the post, I will post this in the homework section...thanks
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
