Tabulate the relative magnitudes of modulus of elasticity of steel to aluminum alloys, copper alloys, titanium alloys, rubber, and wood.

Answer to Problem 48P
The relative magnitudes of modulus of elasticity of steel to given materials are tabulated in Table 1.
Explanation of Solution
The values of modulus of elasticity for the given materials are taken from table 10.5 in the text book.
The modulus of elasticity of steel
Determining the average modulus of elasticity value for aluminum alloy is,
Determining the average modulus of elasticity value for copper alloy is,
Determining the average modulus of elasticity for titanium alloy is,
Determining the average modulus of elasticity for rubber is,
Determining the average modulus of elasticity for steel is,
Determining the average modulus of elasticity for Douglas fir is,
Determining the average modulus of elasticity for oak is,
Determining the average modulus of elasticity for Southern Pine is,
Thus, the determined relative magnitudes of modulus of elasticity of steel to given materials are tabulated in table 1.
The Table 1 shows the material, modulus of elasticity, and the relative magnitudes of modulus of elasticity of steel.
Conclusion:
Hence, the relative magnitudes of modulus of elasticity of steel to given materials are tabulated in Table 1.
