| A fundamental design decision is the
selection of a specific metal composition that best meets the desired performance and production
requirements.
For the pedal components, the mechanical requirements in the critical
areas are:
-- 90 ksi ultimate tensile strength,
-- 50 ksi yield strength,
-- 5% ductility.
These strength requirements have to be met while providing high corrosion
resistance, modulus of elasticity, and hardness, while avoiding excessive weight and
production cost. |
