Be convinced whether is not present on springs of cracks and whether elasticity of springs decreased for what check deformation of springs under loading (fig. 3-48, 3-49, 3-50).

Fig. 3-50. Scheme of check of a spring of the lever:
And — the size in a free state; In — the size under loading

For springs of levers (fig. 3-50) the size A (a spring in a free state) has to be 35 mm, and the size B under load of 51-73,5 N (5,2–7,5 kgfs) — 43 mm.
