Good day Sir , why are you using 0,8× M for the height of the bolt? Isn't it 0,7×M?

[@etutorsdigitalschool2215]

Ohh Yes, Sorry dear silly mistake, it's 0.7 X M

[@SxolileMajola]

When drawing a square Mr, why are we not using the formula 1,5xD. Where D is our diameter of a bolt. Because wena you took a diameter as it. But the text book have given us the formulas. Please explain yhere for me.

I'm confused the question says draw left hand internal V-thread and the thread must slant to the left but yours slanted to the right?

[@etutorsdigitalschool2215]

..... No, they are not to the right

@@etutorsdigitalschool2215 how sir i don't understand?

[@btnyalungu]

Hello Sir isn't the height of bolt head 0.7 then we multiply by the M number?

[@etutorsdigitalschool2215]

Yes, correct

[@btnyalungu]

I'm confused because you multiplied the height of the bolt head with 0.8 instead of 0.7

[@etutorsdigitalschool2215]

Yes, correct that The height of the Bolt 🔩 head is 0.7 X M The height of the Nut is 0.8 X M

@@etutorsdigitalschool2215 Okay thanks for clarity, seems like you made a mistake

Sir, we always plot the pitch as it is? We dont say 0.5x6=3 and use 3 to divide? I'm so confused 😕😢

[@etutorsdigitalschool2215]

Yes, at the first point, we say 0.5xP then after that point we say full pitch til at the end

[@nothandobukhosini7920]

Ohh thank you so much, we do that both up and down?
