26. A semi-elliptical laminated spring has the follow-
ing data :
Length of longest leaf
= 0•8 m
Central load
= 4 kN
%3D
Central deflection
Allowable bending stress = 200 MPa
-= 2 cm
Width to thckness ratio of leaves = 12 : 1
Calculate (a) size of leaves, (b) overlap, (c) number of leaves, and
(d) radius of curvature of leaves.
Take E = 210 GPa.
