Machine Design - Section 1 (3)

In order to obtain the bolts of uniform strength, an axial hole is drilled through the head as far as the threaded portion such that the area of shank becomes equal to the root area of the thread.

When a bolt is subjected to shock loading, the resilience of the bolt should be considered in order to prevent breakage at the

Which of the following material has the maximum ductility?

The value of stress concentration factor depends upon

In order to avoid tearing of the plate at an edge, the distance from the centre line of the rivet hole to the nearest edge of the plate should be equal to (where d = Diameter of rivet hole)

According to Unwin's formula, the relation between the diameter of rivet hole (d) and the thickness of plate (t) is given by (where d and t are in mm)

The square threads are not so strong as V-threads but they offer less frictional resistance to motion than Whitworth threads.

In radial cams, the follower moves
