Answer 1

Concept:

In a riveted joint, the tensile resistance of the plate is determined based on the net cross-sectional area left between rivet holes.

\( P_t = (\text{Net Area}) \times \sigma_t \)

Net area between two rivets = \( (p - d) \cdot t \)

Given:

\( p \) = pitch of rivets (mm)

\( d \) = diameter of rivet hole (mm)

\( t \) = thickness of plate (mm)

\( \sigma_t \) = permissible tensile stress of plate material (N/mm²)

Calculation:

\( P_t = (p - d) \times t \times \sigma_t \)
