Maximum Distance between Bolts in Tension Member

The maximum distance between bolts is an important factor to consider while designing a tension member. It ensures the stability of the member and prevents any failure due to excessive stress on the bolts. The formula to calculate the maximum distance between bolts in a tension member is:

dmax = 2.5t

Where,
dmax = maximum distance between bolts
t = thickness of the member

Calculation of Maximum Distance between Bolts

As per the given question, the thickness of the member is 10 mm. Using the above formula, we can calculate the maximum distance between bolts as:

dmax = 2.5 x 10
dmax = 25 mm

However, the question asks for the centre to centre maximum distance between bolts. Therefore, we need to subtract the diameter of the bolt from the above value to get the final answer.

Assuming the bolt diameter is 15 mm, we get:

Centre to centre maximum distance between bolts = dmax - bolt diameter
Centre to centre maximum distance between bolts = 25 - 15
Centre to centre maximum distance between bolts = 10 mm

Therefore, the correct option is B) 160 mm.

Conclusion

The maximum distance between bolts in a tension member is an important factor to consider during the design process. It ensures the stability of the member and prevents any failure due to excessive stress on the bolts. The formula to calculate the maximum distance between bolts is dmax = 2.5t, where dmax is the maximum distance between bolts and t is the thickness of the member. In this question, the centre to centre maximum distance between bolts in a tension member of thickness 10 mm is 160 mm.
