A remote experiment vs. hands-on

This work describes a Demo to be presented in the Demo Session at exp.at´15, related with an experiment that can be used either as hands-on or as a remote setup. In this way, after lab sessions students may use a totally familiar experiment any time they need to go back to the experimental topic. The electronics and the web server functionality are based on microcontrollers´ capabilities and the sensing system is based on simple and homemade sensing devices. The prototype allows students to compare the mechanical properties of two different materials or offers a more complete investigation by analyzing and comparing results from distinct specimens - materials and/or beam geometries. It also permits to understand easily the concept of stiffness and its relation with Young Modulus and the specimen dimensions.
