Soap film pull on a wire

Soap film pull on a wire is the force created by the surface tension of a soap film stretched across a wire frame.

How big is it?

0.006 N of force

Force · approximate
Typical recorded range: 0.002 N to 0.02 N.

Scale illustration of Soap film pull on a wire, calibrated to its force measurement.
The marked force represents 0.006 N.

A little perspective

Binary-star planet tidal acceleration is about 1.67 times larger on this measurement.

Binary-star planet tidal acceleration: Binary-star planet tidal acceleration is the difference in gravitational pull experienced across a planet due to the influence of two stars.

The marked force is calibrated. Unmeasured illustration details are representative.

Binary-star planet tidal acceleration

A defined 0.01 m/s² differential-acceleration comparison across an Earth-sized planet, expressed as equivalent force on a 1 kg body. It is a model value, not a named exoplanet measurement.

Defined examples — our methodology

The marked equivalent differential force on a 1 kg body is calibrated. Unmeasured illustration details are representative.

Why this measurement?

Why we use 0.006 N

For comparison, this page uses force. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 0.002 N to 0.02 N.
