The Width Of Lacing Bars In mm Is Kept

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.

Rivet diameter( in mm)	Lacing bar ( in mm)
16	50
18	55
20	60
22	65

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.
