I am not very good in maths and physics could I succeed in studying B-tech

* First of all, you have to think are you confident from inner-self ? to move ahead towards B-tech study.

* Are you interested to do this with patience, without taking any worry.

* It is not matter how much you weak in any subject, it is only matter about your choice of confidence in any stream.

* You have to not think like, I am not good in this subject. You have to think like, why I am wanting to go in B-tech study.

* What is main motive for me to doing B-tech.

* Think our-self, Can I only do this because of good package salary or just for high reputation.

* So my friends, its very simple to take decision about yourself.

just talk this worlds with yourself and think on it and then take any decision on it.

Application of elasticity | Physics

 1) while designed concrete or steel structure it is design to bear more load than actual load.

 2) To determine strength of material.

3) In engineering to determine tensile strength of different of different material.

4) The elasticity property has to be taken into account in the construction of building and fly over, bridges etc.

5) When we wind a watch its spring is strained and energy is stored in it as strained energy, the spring slowly rotates inside of the watch due to strain energy.

Defination of stress | Physics

* Ultimate stress: It is the maximum stress with which system is                                          capable of withstanding.

* Working stress: It is the actual load on the system.

* Breaking stress: It is the maximum stress at which wire will breaks.

* Factor of safety: It is the ratio of ultimate stress to working stress.

Difference between elastic body and Plastic body | Physics

                      Elastic body 

Definition: The property on account of which a body regain it's original size and shape on removal of external deforming force is called as elastic body.

Process:  It is reversible.

Ductility: It is less ductile in nature.

Modulus of elasticity: The ratio of stress to strain is low or equal.

Toughness: They have the ability to absorb energy up to fracture.

Bonds: The molecular bonds do not get fractured.

Shape and size: The shape and size does not change permanently.

Example: Rubber.

                               Plastic body

Plastic body: The property on account of which a body doesn't regain its original size and shape on removal of applied force is called as plastic body.

Process: it is irreversible

Ductility: They are highly ductile in nature.

Resilience: They have low yield strength.

Modulus of elasticity: The ratio of stress to strain is high.

Toughness: They do not have the ability to absorb energy up to a fracture.

Bonds: The molecular bonds are fractured.

Shape and size: The shape and size changes permanently.

Example: Plasticine
