The marked weight represents 1.765 N.

A little perspective

About 4.02 times the equivalent force on a 1 kg sample of Ten-metre centrifuge at two rpm.

Ten-metre centrifuge at two rpm: A ten-metre centrifuge at two rpm is a rotating device used to simulate artificial gravity by spinning samples at a controlled speed.

Weight of a 180 g apple

Force on a 180 g apple at standard Earth gravity. Its mass is 0.18 kg.

Defined examples — our methodology

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

Ten-metre centrifuge at two rpm

A defined 10 m radius centrifuge rotating at 2 rpm. It produces about 0.439 m/s² centripetal acceleration, expressed here as 0.439 N on a 1 kg sample; speed and period are derived from the same model.

Defined examples — our methodology

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