Title: Mechanical measurements of small forces

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.
