Answer:
False
Explanation:
The government decides the productions.
Explanation:
Step1
Strength is the maximum stress induces in the material under applied load condition. More the strength more will be ability to sustain load. Strength can be measured from tensile test. It has same unit as stress. Generally ductile material has more strength as compare to brittle material.
Step2
Hardness is the resistance to scratch on the material under given load condition. More the hardness more will be the resistance towards scratching of material. Hardness can be measured by Rockwell or Birnell hardness test. This property of metal is opposite to the strength.
Step3
Toughness is the ability to absorb energy under given loading condition up to its fracture point. It is a type of strain energy that is stored in the metal. Generally ductile metal has more toughness as compare to brittle.
Answer:
The answer is disc brake first evolved as a motorcycle braking system pattern just to become a smaller and remarkably lighter version of them.
Explanation:
- <u><em>It consisted of a metal disc called rotor and callipers that were attached to the fork or frame and equipped with pads to squeeze the rotor for braking.</em></u>
Answer: d) All of the above
Explanation: Crystallization is the process in which a solid crystalline structured material is obtained from the liquid substance. the quantity of crystallization center in crystal may increase due to several reasons like changing the cooling rate or mechanical mixing of the substances or imitation of crystals etc.
These processes end up adding mineral atoms to get attached to the center of crystal and hence increasing the size. Thus, the correct option is option (d).
