1. There are checkboxes: hint: guidelines and arrows to indicate the region of interest plus the accompanying rationale for the answer. answer: shows the measurement d = ??? mm lock: allows simulating of the lock function in real micrometer which disable changes to the position of the spindle then by the measurement is unchangeable.
2. This applet has an object (Black) with the slider on left top to control the y-motion of the object into the anvil and spindle (jaws), the graphics also allows drag action. with the slider on left bottom to control the x-size of the object into the anvil and spindle (jaws).
3. A screw's lead is the distance it moves forward axially with one complete turn (360°). (In most threads [that is, in all single-start threads], lead and pitch refer to essentially the same concept. ) With an appropriate lead and major diameter of the screw, a given amount of axial movement will be amplified in the resulting circumferential movement.
4. The basic operating principles of a micrometer are as follows: The amount of rotation of an accurately made screw can be directly and precisely correlated to a certain amount of axial movement (and vice-versa), through the constant known as the screw's lead.
5. Lock nut / lock-ring / thimble lock (Blue) The knurled part (or lever) that one can tighten to hold the spindle stationary, such as when momentarily holding a measurement.
6. On the bottom, there is a green slider to control the position of the spindle, drag on any part of the view also drags the spindle.
7. On the left bottom slider is the zero error control to allow of exploring with if the micrometer has either +0. 15 mm (max) or -0. 15 mm (min) zero error.
8. Spindle (Dark Green) The shiny cylindrical part that the thimble causes to move toward the anvil.
9. Anvil (Gray) The shiny part that the spindle moves toward, and that the sample rests against.
10. Screw (not seen) The heart of the micrometer It is inside the barrel.
11. Micrometers use the principle of a screw to amplify small distances that are too small to measure directly into large rotations of the screw that are big enough to read from a scale.
1. It's good for learning tool media.. thanks mateIt is really a good app to learn about the screw guage but it is just a 2-d imageVery low quality not working properlyHelps students learn to read analog micometer screw gaugeNot sure why but it kept giving me the same questions over and over.Best app for beginnersBad as hellGood💩Just started using one at work for the first time, great for training purposes.
