How does a lightning rod work?

AI Thread Summary
A discussion on determining the height of a lightning rod based on a protection zone radius of 75 meters highlights the need for calculations in engineering applications. The conversation references a resource found online that may assist in understanding the relationship between the rod's height and its effective radius. The inquiry emphasizes the importance of proper lightning protection for flat-roofed buildings. Participants are encouraged to explore scientific literature for accurate formulas and guidelines. Overall, the thread seeks to clarify the technical aspects of lightning rod specifications.

Greetings community

An engineer came to me seeking help today. He asked me to determining the height of a lightning rod If the radius of the protection zone was given.

Assuming the roof of the building is completely flat, what would the height (h = ?) have to be for a given radius of 75 meters (r = 75m)?

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
