Principle and operation of stylus probe instruments

 Principle and operation of stylus probe    instruments

Direct Instrument Measurements (Metrology):

These methods enable to determine a numerical value of the surface finish of any surface. Nearly all instruments used are stylus probe type of instruments. These operate on electrical principles. Further, these electrical instruments can be of two kinds. In first type, they operate on the carrier-modulating principle. The movements of the stylus exploring the surface are caused to modulate a high frequency carrier current. The second type includes those operating on voltage-generating principle. In these the movements of the stylus are caused to generate a voltage signal. In both these types the output has to be amplified and the amplified output is used to operate a recording or indicating instrument .The carrier modulated frequency type of instruments have the advantage that the signal fed to the recorder depends only upon the position of the stylus. While in the voltage generating type, when the oscillatory movement of the stylus stops, the output falls to zero no matter where the stylus may be.Some pneumatic instruments are also used for measuring surface finish.

12 things that student should not do on social media

Hey guys this is Atchut back with you with some tips for students like us which i found out on Internet lately. 

                 The last thing young people want is another set of rules. But these days, social media comes with great responsibility, whether you’re just starting high school or finishing up college.
The fact is, irresponsible social media conduct could potentially ruin your education and negatively impact your career, not to mention hurt others in the process. (And we’re not just talking kids, either.) But most of those consequences are preventable, often with just a little foresight.
I’ve pinpointed 12 social media mistakes that students should avoid at all costs, because after all, it’s never as simple as “be responsible.” And it’s never as finite as “don’t friend your teacher on Facebook.” Social media circumstances are nuanced and vary by situation, school and user.
Please head to the comments below to add your own contributions and advice for young adults on social media.
