Physic Laboratory by Video Tracker and Visual Basic for Application at Home During Covid-19 Pandemic: Material Elasticity Measurement

Abstract

There are many applications that can be used to support physics laboratory today during Covid-19 pandemic. Video tracker and Visual Basic for Application are the simplest application nowadays. In this work, we present the implementation of Video Tracker and Visual Basic for Application at home to measure elasticity modulus of Sheet-Shaped Material in physics Laboratory. There were two stages performed to obtain elasticity modulus of sheet-shaped material. Firstly, the sample was placed in a curved position (curvature angle variation) then the image was recorded. The result of these photo recording was processed using video tracker software. The data obtained were coordinates point mass of each sheet-shaped material curvature. These coordinate point mass used to calculate elasticity modulus using cantilever beam elasticity equation. Finally, to confirm these results, we also measured directly on the material using a tensile test equipment. The computed results showed that elasticity modulus value closed to value obtained by direct measurement using a tensile strength device. Hence, this method is very potential to develop new ways of practice in physics laboratory.
