The width of lacing bars in mm is kept

  1. Equal to nominal rivet diameter
  2. Twice to nominal rivet diameter
  3. Thrice to nominal rivet diameter
  4. Maximum of the above rounded to nearest 5 mm

Answer: D. maximum of the above rounded to nearest 5 mm.

The width of lacing bars in mm is kept maximum of the above rounded to nearest 5 mm.

Solution

Minimum width of lacing bars shall not be less than approximately 3 times the diameter of connecting bolt/rivet. Hence, the width of the lacing bar is 3 times the diameter of the river (consider the above value rounded to the nearest 5 mm ). Lacing is generally preferred in case of eccentric loads.

The thickness of the lacing flat for a single lacing system should be less than 1/40 of its effective length and for a double lacing system, it should be less than 1/60 of its effective length.
