Reviewed by Calculator Editorial Team

Table B-2 is a reference table commonly used in engineering, scientific, and technical calculations. This guide explains how to properly use Table B-2 for various mathematical and engineering problems.

How to Use Table B-2

Table B-2 provides pre-calculated values for specific parameters. To use it effectively:

  1. Identify the specific values you need to calculate
  2. Locate the corresponding row and column in Table B-2
  3. Read the intersection value for your calculation
  4. Apply any necessary conversion factors

Always verify the units and assumptions when using reference tables. Different tables may have different parameters or units.

Step-by-Step Process

When performing calculations with Table B-2:

  1. Determine the independent variables needed for your calculation
  2. Find these variables in the table's row and column headers
  3. Locate the intersection point of your variables
  4. Read the corresponding value from the table
  5. Apply any necessary formulas to get your final result

Common Calculations with Table B-2

Table B-2 is commonly used for:

  • Engineering stress calculations
  • Thermodynamic property lookups
  • Material science property references
  • Electrical engineering component values
  • Mechanical design factor calculations

When using Table B-2 for stress calculations, remember that:

σ = F/A

Where σ is stress, F is force, and A is cross-sectional area

Example Scenarios

Table B-2 can be applied to various practical scenarios including:

  • Determining safe load limits for structural components
  • Selecting appropriate materials for specific temperature ranges
  • Calculating heat transfer coefficients for different materials
  • Selecting electrical components based on voltage and current requirements
  • Determining material properties for manufacturing processes

Example Calculation

Let's walk through a sample calculation using Table B-2:

Problem Statement

You need to determine the allowable stress for a steel component operating at 200°C with a safety factor of 2. Table B-2 provides the ultimate tensile strength for various materials and temperatures.

Solution Steps

  1. Locate steel in the material column of Table B-2
  2. Find the row corresponding to 200°C
  3. Read the ultimate tensile strength value (e.g., 450 MPa)
  4. Divide by the safety factor: 450 MPa / 2 = 225 MPa

Result

225 MPa

This is the allowable stress for the steel component at 200°C with a safety factor of 2.

Verification

Always cross-check your results with other reliable sources or perform additional calculations to ensure accuracy.
