Per Ericson + Catto, COULOMB FRICTION at a contact is typically modelled with friction force bounded by which?
AMass of the lighter contacting body only
Bμ × normal force (the friction cone)
CVelocity squared at the contact point
DVolume of the larger of the two bodies
Answer & Solution
Correct answer: B. μ × normal force (the friction cone)
Ericson + Catto: tangent friction force magnitude ≤ μN. Stick if below limit; slide at limit. Modeled as a cone (3D) or wedge (2D).
