 When the rotating part rotate one complete cycle, it move 0.5 mm distance (the main scale increase by 0.5mm). And there are 50 divisions for one complete cycle. So the smaller scale (one division) is 0.5/50=0.01 mm |

Registed user can get files related to this applet for offline access.Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list If java program did not show up, please download and install latest Java RUN TIMEThe total length for the scale of the moving part is 19mm. And it was divided by 10 divisions, so each division is 1.9mm which is less than two units in the main scale by 2.0-1.9mm=0.1mm. Think of the above system in the following way: Assume every 2.0 mm in the main part is replaced by a 2.0mm block. And every 1 division in the moving part is replace by a 1.9mm block. If the first block of both part are aligned at the right, then there is a 0.1 mm displacement at the left. If the second block of both part are aligned at the right, then there is a 0.2mm displacement at the left. ... I hope you can understand what I mean. Anyway, I am going to create another java applet to show it. Drag the slider to change the alignment points. Assume the top block is 2.0mm each, and the lower one is 1.9mm each (total length =1.9mm*10=19mm)

Thx for the great program. I'm in my first semester taking electromechanical classes at a tech school and we have had limited time in lab to get familiar with calipers and vernier scales. This program really helped reinforce what I learned in lab and it really showed come test time. thx again |

I am wondering if anyone has had any experience using Vernier's LabPro data collection device with Linux. While I am familiar with their Linux page, I do not understand most of it. I am experienced with using the LabPro on Windows and Mac, but I would really like to know if anyone has successfully used it with Linux in a classroom environment. |

Dr Hwang, I'm very thankful you have made all these simulations. As a secondary school physics teacher, i find the apps very useful for both demos and exam setting. On another thing, the Creative Commons license basically says I can share these apps, as long as you are acknowledged. I would like to post your apps into my website, as to help make it more interactive for the students I teach. Your approval would be very much appreciated. Thank you very much! |

You are welcomed to distribute simulations I have created. You can even modify the simulation if EJS has been installed in your computer. Enjoy the fun of physics! |
