Fc
1.4 kip
FA
The length of each segment is given by:
a
b.
4 in
13 in 7 in
If the all-thread is composed of a material that has an elastic modulus of 31000 ksi, and its effective diameter
is 0.7 inches, determine the following
(a) The maimum normal stress in this piece of all-thread.
(b) The change in length of segment AB.
(c) The change in length of segment BC.
(d) The change in length of segment CD.
(e) The change in length of the whole length of all-thread.
Under the following assumptions:
Bearing stress between threads of the allthread and the nut may be neglected
Stress concentration effects may be neglected
• The forces that the nuts apply may be treated as concentrated forces at each location
• The nuts may be treated as rigid.
• The force applied to each nut is distributed evenly around the nuf's perimeter.
(a) oma
(b) SAB=
(c) Snc
(d) deD
(e) tal
• be sure to include units with your answers
• denote tensile stresses and elongations with positive values compressive stresses and compactions with
negative values
