Objective: Measure the surface tension by the “breakaway” method To determine the surface tension of a liquid, a blade is immersed horizontally in the liquid and is slowly pulled out upwards while measuring the pulling force ... more

A flat, level beam’s resistance to deformation in the form of bending by an external force can be calculated mathematically if the degree of deformation is much smaller than the length of the beam. The deformation is proportional ... more

In order for solid bodies to be deformed, an external force needs to be applied. This acts against the body’s own resistance to deformation, which is dependent on the material from which the body is made, as well as its geometry ... more
