5.4 ⚫ BIO Injuries to the Spinal Column. In the treatment of
spine injuries, it is often necessary to provide tension along the spi-
nal column to stretch the backbone. One device for doing this is the
Stryker frame (Fig. E5.4a, next page). A weight W is attached to
the patient (sometimes around a neck collar, Fig. E5.4b), and fric-
tion between the person's body and the bed prevents sliding. (a) If
the coefficient of static friction between a 78.5 kg patient's body and
the bed is 0.75, what is the maximum traction force along the spi-
nal column that W can provide without causing the patient to slide?
(b) Under the conditions of maximum traction, what is the tension in
each cable attached to the neck collar?

The correct answers are a) 367 hours, b) 7.42*10^9 Bq, c) 1.10*10^10 Bq, and d) 7.42*10^9 Bq. Yes I am positve they are correct. Please dont make any math errors to force it to fit. Please dont act like other solutiosn where you vaugley state soemthing and then go thus, *correct answer*. I really want to learn how to properly solve this please.
