Parallel-gripper friction hold
Inputs
User-entered payload mass for the stated friction-only vertical hold screen.
User-entered upward acceleration magnitude; trajectory and dynamic shock are excluded.
User-entered friction coefficient strictly greater than 0 through 1; contact behavior is not predicted.
Count of equally sharing parallel grip contacts for literal per-jaw force arithmetic.
User-entered multiplier used only in the visible friction-hold arithmetic; it is not a safety approval.

Method
Formula, when it applies, and when it does not
Calculate friction-only vertical-hold normal force and per-jaw force share from payload, acceleration, friction, jaw count, and multiplier inputs.
Fgrip = m(g + a)·S/μ; Fj = Fgrip/z
When
- Parallel friction grip
- Vertical declared acceleration
- Uniform stated jaw-force sharing
- User-entered friction and multiplier
Don’t
- This applies a declared friction-only vertical-hold relation for equally sharing parallel grip contacts. It does not select a gripper, jaw, pad, pressure, or actuator; calculate contact geometry/stress, lateral or moment loads, compliance, force curves, dynamic shock, payload security, safety, suitability, or approval.
