$\bullet$ Dislocated shoulder. A patient with a dislocated shoulder is put into a traction apparatus as shown in Figure $1.29 .$ The pulls $\vec{A}$ and $\vec{B}$ have equal magnitudes and must combine to produce an outward traction force of 5.60 $\mathrm{N}$ on the patient's arm. How large should these pulls be?

In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

In mathematics, algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

So now we're going to be doing Chapter one problems 63. And this, as a patient with a dislocated shoulder, is put into a traction apparatus. As shown in this figure. So strong figures is the guy's arm puts in apparatus here with a horse is out this way in this. So I call this one a appear this need and both of those are 32 degrees from the parallel arm. So the holes a nd of equal magnitude is same directions so they could morte. They combined to produce an outward traction force of 56 mutants. So that means the's combined to be a year 56 and use as a result, inspector. Okay, so we want to figure out what's the magnitude and be from this. So to set this up, we know that our accident end up being 5.6 G's, so a X b x c equals 5.6. Great. Since I am B are the same, we could actually just say two ex, and now we can use the 32 degrees the trigonometry. Byrne replaced a backs in terms of the magnitude. So this is equal to two a magnitude times go sign to get the X value of the angle. Perfect. So this equals 5.6 Newtons. And now we just have to rearrange this equation and we consult for a So this makes a need to be a 3.3. It's which also equals B, and that's well, that is it perfect.
