\[F=\sigma A\]
Variables
Fmuscle force (N)
sigmamuscle stress (Pa)
Amuscle cross-sectional area (m²)
Description
What is this formula?
This formula calculates the linear force generated by a muscle based on the muscle stress and its physiological cross-sectional area. It is widely used in biomechanics and muscle physiology.
When to use it
Use this formula when estimating the force-producing capacity of skeletal muscles in biomechanical or physiological analyses.
Example
A muscle has:
sigma=3.0×10^5 Pa
A=8.0×10^-4 m²
Formula:
F=sigma*A
Substitution:
F=(3.0×10^5)*(8.0×10^-4)
Result:
F=240 N
The muscle can generate approximately 240 N of force.
