Q: Page 72. There is some misunderstanding about λ0_Tcy_Units, λ0_Unit_mech and λ0_Tcy_casing, λ0_casing_mech?
This are translation mistakes. The word "case" should have been used instead of "casing" or "unit". Therefore, in this page: λ0_Tcy_case shall be read instead of λ0_Tcy_Units or λ0_Tcy_casing. λ0_mechanical_case shall be read instead of λ0_Unit_mech or λ0_casing_mech.
