In engineering calculations, shear stresses are very important aspects. Shear stresses must be calculated neatly to see the designed system is safe or not. In general, engineers calculate the maximum shear stresses that occur on different cross-sections.

These maximum shear stresses are compared with the material’s boundary shear stress value to see whether the system is safe or not.

Here, we show you how to calculate the maximum shear stresses on different cross-sections.

First of all, you need to understand the calculation of shear stresses generally.** **But you can find the maximum shear stresses easily for certain cross-sections.

‘b’ is the width of the rectangular cross-sectional area and ‘d’ is the height of the rectangular cross-sectional area. Shear force ‘V’ is acting vertically to this cross-section, which perpendicular to ‘b’. In this case, you can calculate the average shear stress by using this calculator.

To use this calculator, enter the required values then click on the ‘Calculate!’ button. To make another calculation, click on the ‘Reset’ button then re-enter the values.

Consider the same shear force acting upon the circular cross-section. In this case, you can calculate the maximum shear stress via this calculator;

Here, ‘r’ is the radius of the circular cross-section and the ‘V’ is the shear force.

Consider the height of the triangular cross-section is ‘H’ and the base length of the triangular cross-section is ‘B’ Then the maximum shear stress is;

Here, ‘r’ is the radius of the circular cross-section and the ‘V’ is the shear force.

For these tubular cross-sections, consider the thickness of the tubular cross-section is ‘t’ and the radius of the cross-section is ‘r’. So the maximum shear stress occurs on this cross-section can be calculated via this calculator;

These cross-sections are generally the most used cross-sections in structural design.,

Use consistent sets of units for lengths and the other types of units to obtain correct results from calculators. To obtain consistent sets of units, you can use the MB-Unit Converter tool.
