A 2014-T6 aluminum tube having a cross-sectional area of 600 mm² is used as asleeve for an A-36 steel bolt having a cross-sectional area of 400 mm², When thetemperature is T=15 °C, the nut holds the assembly in a snug position such that theaxial force in the bolt is negligible. If the temperature increases to T-80 °C and anaxial force of 25 KN is applied to the assembly, determine the stresses in the bolt andthe sleeve. Note: Length of the assembly is 150 mm, E is 200 Gpa, a is 12*106 (forbolt), E is 73.1 Gpa, a is 23*106 (for sleeve).

Properties of Aluminium

Aluminum (or Aluminum) is a silvery-white in color metal. The chemical symbol of aluminum is Al and it has an atomic number (Z) of 13 in the periodic table. The aluminum name for this metal is derived from the Latin word ‘alumen’, which means bitter salt. Aluminum was discovered in the year 1825 by Hans Oersted, and later Friedrich Wöhler isolated aluminum. It is the most commonly found metal in the earth’s core, which is around 8% of the total core mass. Moreover, it is the third most commonly found element on earth after oxygen and silicon. Electron distribution of aluminum per shell is 2, 8, and 3 with a valency of 3. Atomic weight is nearly 26.9815 u.

A 2014-T6 aluminum tube having a cross-sectional area of 600 mm² is used as a
sleeve for an A-36 steel bolt having a cross-sectional area of 400 mm², When the
temperature is T=15 °C, the nut holds the assembly in a snug position such that the
axial force in the bolt is negligible. If the temperature increases to T-80 °C and an
axial force of 25 KN is applied to the assembly, determine the stresses in the bolt and
the sleeve. Note: Length of the assembly is 150 mm, E is 200 Gpa, a is 12*106 (for
