Your boss hands you a bag containing four springs, A, B, C, and
D, and tells you that they all have the same relaxed length. He
wants you to rank them by the values of their spring constants. He
locks you in a room with only the springs, a ruler, and a pad and
pencil, and tells you to knock when you're done. Each spring has a
hook on one end and a handgrip on the other. There is nothing in
the room you can use to measure inertia.
After thinking for a few minutes, you hook springs Aand B together,
stand on one handgrip with your foot, and pull on the other
handgrip with your hand until the combination spring has been
stretched to double its original length (Figure 1). You notice that
spring Amakes up 65% of the stretched length and spring Bmakes up
the other 35%. You work your way through the rest of the springs
and tabulate the results:
Combination | Percent of stretched length |
A/B | A 65, B 35 |
A/C | A 70, C 30 |
A/D | A 67, D 33 |
Based on these results, what is the ratio kA/kB?
Express your answer using two significant digits.\
PLEASE GIVE Kb/Kc and Kc/Kd. I already know Ka/Kb, Ka/Kc, and Ka/Kd. Thanks!
(The answer to the first question is not 35/65 or 0.54. It was 0.25).
