Question
Now, calculate the compressive force acting on the lumbar vertebra.
Report the force, in units of N, to 0 decimal points (e.g. 101 N). You are
allowed an error margin of +/- 10 N from the exact correct answer.
Positive or negative values will be accepted.
Here is information you may need to solve this problem:
• The GRF is 225 N.
• The GRF has a moment arm of 0.40 m relative to the vertebra axis of
rotation.
• The weight of the trunk is 350 N.
• W trunk has a moment arm of 0.3 m relative to the vertebra axis of
rotation.
● Fm is 300 N.
Fm has a moment arm of 0.05 m relative to the vertebra axis of
rotation.
