Mechanical measurements of small forces

December 6, 2021 - 11:00am
Stephan Schlamminger

Abstract: The absolute and precise measurement of small forces and torques is a difficult task. I will give examples of small forces from several research topics, for example, measuring the gravitational constant, photon pressure forces, and new ways to calibrate torque screwdrivers. Several techniques, their strengths, but also their pitfalls will be illuminated. Thus, the audience will learn several valuable and fun metrological tools and gain an appreciation of the usefulness of these measurements to advance physics and society.

Joint Quantum Institute Seminars take place live each Monday during Fall and Spring Semesters, 11:00 a.m. - 12:00 p.m. Eastern Time, in Room 2400 of the Atlantic Building. University of Maryland affiliates may participate using Zoom. The Seminars are also simulcast world-wide on the Joint Quantum Institute YouTube channel, , which supports audience participation in the chat interface.
