Question

Imagine the human life with out metals. Write a 10 points on it

Answer 1

Answer:

Metals are solid substances obtained from the earth. Metal uses are many and this is due to their natural properties of rigidity, ductility, tensile strength etc.

They are very strong, durable and highly resistant to natural wear and tear.Hence they have been used widely by man since ancient ages.In past these metals were profoundly used for cooking, farming tools, weapons (bow, arrows, swords) and also in locomotive wagons.But with growth in technology, the horizons of their use has widened enormously.Currently, almost any object produced by use of technology uses metals in one or other form.

Imagine what happens if we stop using metals in day today life they are following :

1.In electronics: Electronics are the equipment which largely rely on electricity to function. We use many electronics like TV, mobiles, fridges etc. in daily life.Imagine life without those things because if metal is not use then how your electricity/ current pass.

2. In medicine: Metals are available as micro-elements in our body. They are needed for conduction of nerve impulses, to carry oxygen by blood, to facilitate enzyme reactions and more. So metals are used in medicine to cure any micronutrient metal deficiency diseases in humans and animals. Ex. iron is a part of hemoglobin a biomolecule. Hence it is used as ferrous sulfate to cure some forms of anemia.Then,imagine life without medicine.

3. In building construction: Metals like iron and steel are widely used in building and home constructions. Their strength and ability to withstand heavy weights make them preferred in construction. They are commonly used in reinforced concrete roofing, pillars, foundations, fencing etc.

4. In jewelry: Metals like Gold, silver, platinum, copper are widely used in jewelry. These metals are symbolic of financial status and hence very expensive. No metal no jewellery.

5. In machinery & automobiles: Many machines and automobiles are made of metals extensively. Metals which can withstand high temperature and pressure during work are preferred. The commonly used metal is Iron, steel, aluminum etc. so cranes, mills, satellites. The machines and automobiles include road vehicles, railways, airplanes, rockets etc.

Besides these, metals are the only sought materials to store and transport gasses under pressure. Cylinders are tanks to store metals are exclusively made of metal to store and also safely dispense the gas when needed.Without use of metals no means to engineering.

6. In cooking: Utensils are best made from metals like steel, aluminum, and copper. Stoves, furnaces, Bowels, troughs, spoons, knives used in the kitchen are made from metal. They are so much preferred as they can withstand temperature and also used for wet and dry purposes.

Imagine life without all things. No metal then no life remains because our body also works on these. Without metal there is no planet, no earth, no universe.

In my Engineering point of view life without metal is like this.
