 What is vernier caliper

Is a device used to measure the length of small objects to the accuracy of 0.01cm.



The parts of vernier caliper.

1. Outside jaws

2. Inside jaws 

3. Vernier scale 

4. Main scale 

5. Lock nut 

6. Depth probe 


Uses of vernier caliper 

1. Used to measure width.

2. Used to measure length.

3. Used to measure inner diameter 

4. Used to measure outer diameter.

5. Used to measure depth.


Procedure on how to use vernier caliper.

What are the procedures?


Limitations of vernier caliper 

1. Has small range of measurement 

0 - 15 cm 

It can measure up to 15 cm or 150 mm

2. Can measure solid objects.

4. Involves calculations

After measurement you Have to perform addition and multiplication.


Digital vernier caliper 


This is the alternative to analogy vernier caliper.


This is digital vernier caliper 

Simplifies calculations since it gives the full measurement results.

Mtaala mpya shule za sekondari 2025

Image
 Taasisi ya elimu Tanzania (TET) Baada ya shule kufunguliwa haya ndio mambo ambayo taasisi ya elimu Tanzania TET na wizara ya elimu Tanzania wametaka wazazi, walimu na wadau wa elimu kuyajua kuhusu mchakato wa Mtaala mpya kwa shule za sekondari kwa mwaka 2025 Imesema kuwa mwaka 2025 mtaala mpya kuanza kutumika.  Katika Mtaala huu kuna mabadiliko machache kama vile. * Somo la civics kuondolewa na kuwekwa somo jipya la historia ya Tanzania na Bofya link/ kiungo hapo chini kutazama video ya maelekezo  https://youtube.com/shorts/0l1eIOVX6qs?feature=share maadili. Somo hili litafundishwa kwa lugha ya kiswahili kuanzia kidato cha kwanza mwaka huu 2025. *Somo la commerce kuondolewa na kuanzishwa kwa somo jipya la elimu ya biashara (business education) Wizara ya elimu na taasisi ya elimu imefanikiwa kuanzisha Mtaala huu mpya kwa mwaka huu 2025 Pia elimu ya amali (mafunzo ya ufundi) nayo kuanzishwa kwa baadhi ya shule, hii ni kutaka kuwajengea wanafunzi uwezo wa ubunifu na ujuzi ...

PHYSICS MTAALA MPYA, NI MZURI NA NI WA KUJENGA KAMA WANAFUNZI WATAFANYA KWA VITENDO

Image
Taasisi ya elimu Tanzania Mwaka 2025  Umetoa muongozo jinsi ya mtaala ulioboreshwa wa elimu ya sekondari utakavyokuwa, hasa kwenye somo la fizikia ambalo limesisitizwa kuwa liwe ni somo linalojenga maarifa ya vitendo ili kuandaa wanafunzi ambao wataweza kuendana na kasi ya maendeleo ya sayansi na teknolojia. Wadau wa elimu wanatakiwa kusimamia hilo ili kuwajengea wanafunzi umahiri mkubwa katika masomo ya sayansi ikiwemo fizikia. Sisi pia kama wadau wa elimu Tanzania tutakuwa tunakuletea machapisho mbalimbali ambayo yatakuwa yakakusaidia namna ya kufundisha somo la fizikia na kulifanya kwa vitendo Ili kuweza kuwajengea wanafunzi uwezo wa ubunifu katika nyanja mbalimbali. Machapisho yetu yakakusaidia mdau wa elimu, mwanafunzi na mwalimu katika harakati za kutekeleza mtaala ulioboreshwa. Hapa tutakuletea namna ya kujibu maswali ya fizikia katika mtaala mpya ulioboreshwa wa competance based. Maada zilizomo katika kitabu cha physics kidato cha kwanza katika mtaala ulioboreshwa  1. ...
