Asemi-elliptical spring has ten leaves in all, with the two full length leaves extending 625 mm. it is 62.5 mm wide and 6.25 mm thick. design a helical spring with mean diameter of coil 100 mm which will have approximately the same induced stress and deflection for any load. the young's modulus for the material of the semi-elliptical spring may be taken as 200 kn/mm2 and modulus of rigidity for the material of helical spring is 80 kn/mm2

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
