Jab aap cylinder fix karletay hain tho aap check kejiay ga k vernier scale ki konsi line main scale k Kisi line k 7 coincide karta hai. Wo value least count se multiply karo tho B ajayega

Late today inshaAllah

Noted .. next video (screw gauge) will be more detailed... Uploading it tonight. Thanks for positive suggestions

1: join the jaws of Vernier Callipers and check whether the zero of Vernier scale coincides with the zero of main scale or not. 2. If they don't coincide there is a zero error. 3. The zero error is positive if the zero of Vernier scale is to the right of zero of main scale and it's negative otherwise. 4. The positive zero error is subtracted from the final result whereas the negative error is added to the final result

One division on the main scale (1 mm) divided by the number of divisions on the vernier scale..

@@physicswithatifwaqas8398 smallest division on main scale =1mm And Total number of division on Vernier scale =10 So LC=0.1mm

@@Haseeb.Saif. there are 20 divisions on the vernier scale.

@@physicswithatifwaqas8398 sir kindly check it, there are 10 divisions on Vernier scale

@@physicswithatifwaqas8398 and you are also saying that number of division are10 during your lecture

Kya smjh nhi aya?
