31materials testing — Introduction measurement of the characteristics and behaviour of such substances as metals, ceramics, or plastics under various conditions. The data thus obtained can be used in specifying the suitability of materials for various… …
32Nuclear bunker buster — Subsidence craters left over after underground nuclear (test) explosions Bunker busting nuclear weapons, also known as earth penetrating weapons (EPW), are a type of nuclear weapon designed to penetrate into soil, rock, or concrete to deliver a… …
33Io (moon) — ] Unlike most satellites in the outer Solar System (which have a thick coating of ice), Io is primarily composed of silicate rock surrounding a molten iron or iron sulfide core. Most of Io s surface is characterized by extensive plains coated… …
34Solid solution strengthening — is a type of alloying that can be used to improve the strength of a pure metal. The technique works by adding atoms of one element (the alloying element) to the crystalline lattice another element (the base metal). The alloying element diffuses… …
35Strength of ships — The strength of ships is a topic of key interest to Naval Architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly… …
