Question
Solve the problem in Example 5.5 using coontinate axes where the $y$ -axis is vertical and the $x$ -axis is horizontal. Do you get the same answers using this different set of axes?
Step 1
We have a picture frame and we are using the coordinate axes where the y-axis is vertical and the x-axis is horizontal. The weight of the frame is acting along the negative y-axis. There are tension forces acting on the frame which we denote as P. The angles are Show more…
