To find the radius whose circumference is equal to 6 feet, we follow the steps below: Write the circumference as c = 6 ft. Recall the formula for the radius of a circle from circumference: r = c / (2 * π). Inject the circumference into the equation: r = (6 ft) / (2 * π) = 3/π ft.
WebApr 13, 2024 · Hi, I am working with leaf springs and studying the derivation of the formula for the deflection of such a structure. The derivation is shown here: My only doubt is how to obtain the following formula: where: - deflection, - length of the beam, - curvature radius. The beam under consideration is simply-supported with force applied in the middle.
