Caliper Simulator is an app that designed to simulate the technique of how to read of Caliper measurement results. This app is one of Computational Lab of Department Physics, UB productivity to increase the passion of learning about physics on Elementary Physics Lab. You can long press the Caliper Image to interact with it, and learn how to measure bolts, head bolts, small iron and something else. The reason why we just give the simulator, and not with the hand book or something else is becaus
