SUMMARY
The minimum diameter of a drum for winding a 4mm thick copper strip, ensuring that the maximum bending stress does not exceed 332 MN/m², is calculated using the formula for radius of curvature. Given the modulus of elasticity (E) of copper as 95 GN/m², the derived radius of curvature (ρ) is approximately 1.7m. Consequently, the minimum drum diameter is 3.4m, as the diameter is twice the radius. The calculation confirms that the bending stress remains within the specified limits.
