Explain why steel is more elastic than rubber |
|
Answer» Steel show more ductility properties than rubber that is why steel is more elastic than rubber. Because steel has more capacity of stress than rubber Because steel has low stress than rubber or we can say steel has low ductility than rubber because steel has ductile property and rubber dont have it |

What is the application of elasticity of modulus?? |
|
Answer» Today finds flexibility ?? As the term implies, "Modulus of Elasticity” relates to the elasticity or "flexibility" of a material. The value of modulus of elasticity is very much significant relating to deflection of certain materials used in the construction industry. Take for example the general E value of mild carbon steel is about 200 GPA comPAred to about 70 GPA for aluminum. This simply translate that aluminum is 3 times flexible than steel.\xa0It indicates that how a material will behave under the application of load. An elactic material has more tensile strength and it can be stretched to a greater extent like steel. So basically good to resist tension at the time of bending. |

Answer» Very nice soumita ji please answer manjeet question also ???? 1. All the non zero digits are significant.2. All the zeros between two non zero digits are significant.3. All the zeros to the left offirst non zero digitare not significant.4. All the zeros to the right of the last non zero digit are not significant.5. All the zeros to the right of the decimal point and to the left of a non zero digit are not significant.6. All the zeros to the right of last non zero digit in a no. with a decimal point are significant.7. When a no. is expressed in exponential form the exponential term doesn\'t affect the no. of significant figure. |

State and explain Bernoulli\'s theorm |
|
Answer» With increase in speed of liquid decrease in pressure of liquid Bernoulli’s theorem states that whenever there is an increase in the speed of the liquid, there is a simultaneous decrease in the potential energy of the fluid .There is a decrease in the pressure of the fluid.Basically, it is a principle of conservation of energy in the case of ideal fluids. If the fluid flows horizontally such that there is no change in the gravitational potential energy of the fluid then increase in velocity of the fluid results in a decrease in pressure of the fluid and vice versa. |
