Question
In example 4.4 "The Principle of Moments" the problem is that of a diver in preparation for a back ip . The diver weighs 80 kg and stands on the very edge of a diving board, momentarily supporting all of their weight on a single foot.
How does the force in the Achilles tendon compare to the weight of the diver?
Question 8 options:
We don't know the force on the Achilles tendon
The force on the Achilles tendon is MUCH more than the weight of the person.
The force on the Achilles tendon is about the same as the weight of the person.
The force on the Achilles tendon is MUCH less than the weight of the person.,
Select the terms that describe the position of the object shown here.
Question 6 options:
stable equilibrium
static equilibrium
unstable equilibrium
dynamic equilibrium

Explanation / Answer
Part 1: Answer would be the 2nd option i.e. the force in Achilles tendon is much more than the weight.( If the diver would have been in preparation of a front flip, then the force in Achilles tendon is much less than the weight).
Part 2: The object shown is in unstable equillibrium as if it is slightly disturbed than it willn't regain its position.
