sholder bolt 01

This shoulder bolt is composed of hot-rolled monel. The head of the shoulder bolt is a regular hexagon and it measures 13 mm across opposite flats. The other dimensions of the bolt are given below, as well as the forces to which this component is subjected. Find the change in length of each segment of the part as well as the overall change in length from A to D.

$F_A$	$F_B$	$F_C$	$F_D$
26.9 kN	30.4 kN	4.8 kN	8.3 kN

a	b	c	$d_s$	$d_t$   (effective)
7 mm	7.4 cm	13.5 cm	10 mm	6 mm

Assume:
$\bullet$ Bearing stress between threads of the bolt and the nut may be neglected
$\bullet$ Stress concentration effects may be neglected
$\bullet$ The force that the nut applies may be treated as a concentrated force.
$\bullet$ The nut may be treated as rigid.
$\bullet$ The forces applied to the nut and the shoulders of the bolt are distributed evenly around their perimeters.
