The maximum centre-to-centre distance (pitch) between rivets in a tension member is governed by structural steel design codes, typically IS 800. The code specifies limits based on the member's thickness to ensure structural integrity.
According to IS 800:2007, Clause 10.2.1.1 and Table 19, the maximum pitch ($p$) for rivets connecting components of a tension member is generally limited by the expression:
$ p_{\text{max}} \le 16t $
where '$t$' is the thickness of the thinner connected plate.
Given the thickness of the tension member is $t = 12 \text{ mm}$.
Substitute the value of '$t$' into the formula:
$ p_{\text{max}} = 16 \times 12 \text{ mm} $
$ p_{\text{max}} = 192 \text{ mm} $
Therefore, the maximum centre-to-centre distance between rivets is $192 \text{ mm}$.
Morgenthau's principles of political realism are:
A. Politics is rooted in permanent and unchanging human nature which is basically self centred, self-regarding and self-interested
B. Politics is an autonomous sphere of action and cannot therefore be reduced to morals
C. International Politics is an arena of conflicting self-interests
D. The ethics of international relations is situational ethics which is very different from private morality
