Mechanical parameters

Parameter	Symbol	Value	Source
Spasmoneme stiffness	κ	∼400 nN	Maximum force (23)
Stalk extensional modulus	Ye	∼1 MPa	Incompressibility
Stalk Young's modulus	Y	∼1 kPa	Simulations
Stalk shear modulus	G	∼0.33 kPa	Elasticity relations
Medium viscosity	η	1 cP	Viscosity of water

These parameters are material properties and are independent of the size of the organism.
