Engineering Calculator

Below is a categorized listing of the engineering calculators, along with the instructions, reference material, and validation for each calculator.

Our engineering calculators are free to use. If you would like us to add a new engineering calculator, please contact us and provide details of your engineering challenge and calculator required. We do not charge for developing and publishing engineering calculators on iCalculator, charges may apply if you require the calculator to be published.
This pipe thickness calculator calculates required pipe thickness for a process pipe based on ASME B31.3 Code. Detail information about behind the back calculations is given at the end of this calculator. This calculator calculates required thickness of a pipe under internal pressure based on criteria specified in section 302.1.1 and 302.2.2 of ASME B31.3 Pressure Piping.
The Department of Physics, Engineering & Geosciences offers courses in Astronomy, Engineering, Geology, Meteorology, Physics, and Physical Science appropriate for all levels of student need. We are the primary source for academic advising for students planning transfer into bachelor's degree programs in all branches of the engineering.

The bolt torque calculator can be used to calculate the torque required to achieve the desired preload on a bolted joint.

The bolt pattern calculator allows for applied forces to be distributed over bolts in a pattern.

The lug calculator allows for analysis of lifting lugs under axial, transverse, or oblique loading.

The column buckling calculator allows for buckling analysis of long and intermediate-length columns loaded in compression.

The Mohr's circle calculator provides an intuitive way of visualizing the state of stress at a point in a loaded material.

The stress-strain curve calculator allows for the calculation of the engineering stress-strain curve of a material.

The cross section builder allows for the calculation of properties for custom cross section.

The stress concentration calculator provides a set of interactive plots for common stress concentration factors.
