The formula to calculate the Modulus of Resistance (R) is:
\[ R = S \times \sigma \]
Where:
The modulus of resistance is a measure of the strength of a material section under bending. It is calculated by multiplying the section modulus by the yield strength of the material. This value is crucial in structural engineering and design, as it helps determine the load a structural element can withstand before yielding.
Let's say the section modulus (S) is 200 cm³, and the yield strength (σ) is 250 MPa. Using the formula:
\[ R = 200 \times 250 = 50000 \]
So, the modulus of resistance (R) is 50,000 N·cm.
