    sir pitch is p= 40mm

    strength of solid plate is governed by yielding not by rupture

      In Books(N.Subramanian & S.K Duugal) also they used Rupture Formula For Finding Efficiency.

    Bolt values calculations aren't clearly explained 32:00 mins , Without clear explanation skipped.
    Not proper Explanation..

    22:15 .. in sub question b) for Vdpb sir you took t =8mm which is of cover plate but for sub question c) for Vdpb you took t=10mm and why not 8mm bcz in question cober plate is of 8mm

    cover plate aur main plate ke beech mein 6 bolts lagenge na ki 3 jaisa in mahashay ne bataya hai
    completely unexpected how can the level of iit kgp be so low ,cant understand

    The no of bolts required is 6 (@14.50) ,so it means 6 on each side in a butt joint, then why is he providing only 3 on each side (@16.45)?

      yes, you are right. total 12 and 8 bolts will be provided in question 1 part b and c respectively.

    I think efficiency should be calculated here with respect to yielding of gross section rather than rupture.....

    While designing Single Cover butt joint, instructor didn't account Reduction factor for packing plate in determining Design Shear Capacity of Bolt.

    sir why we take min bolt value?

    • @Sanjaykumar-nz4tf
      @Sanjaykumar-nz4tf 5 ปีที่แล้ว +1

      At minimum bolt value only bolt starts to fail....
      If bolt value is higher there is no chance for failure....

    pitch = 2.5d = 2.5*16 =40mm not 50 mm.

      According to clause 10.2.2 of IS 800:2007 minimum pitch= 2.5 d, where d is the nominal diameter of the bolt.
