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.

Question

Problem 2: What is the U value for these cases?
1. Plate connected using bolts (fasteners) only.
2. Plate using transverse welds only
3. 3/4 in thick plate using longitudinal welds only where the length of the weld (L=10
in) and L = 1.25 W where W is the width of the plate.
4. Single angle where both legs are bolted to the support.
5. Single angle L8x8x1 with longitudinal welds (L = 9 in) on one leg
6. Channel C10x20 connected using one bolt only in the web
7. Single angle connected on one leg using transverse and longitudinal welds.

Expert Solution

Step 1

NOTE : As per guidelines. first 3 parts are solved. Request you to post remaining parts separately. Thanks

The U value stands for shear lag factor which refers to the reduction in shear capacity of a bolted plate due to the uneven distribution of shear stresses across the width of the plate.
