Which has more skin a mouse or an elephant?
Smaller size animals have more surface area per unit volume than bigger size animals more hair is present on mouse and higher metabolism so that they lose their heat through the skin. The ratio of skin to body weight causes heat lost by mouse is far more than elephant.
Why is steel is more elastic than rubber?
So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.
Which is more elastic water or air or solid or Crystal?
Answer. Water is more elastic than air because bulk modulus of elasticity is reciprocal of compressibility and air is more compressible than water.
Which is more elastic crystal or solid?
1), an amorphous solid has two typical behaviors, which depend on the extent of volume and shear strains. In the stable region, the amorphous solid is truly elastic and reversible, just like crystals. The study shows that a more complete elastic theory is needed – one that can correctly incorporate amorphous solids.
What is more elastic water or copper?
Bulk modulus of water is greater than that of copper.
What is state Hooke’s Law?
Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. Hooke’s law describes the elastic properties of materials only in the range in which the force and displacement are proportional. (See deformation and flow.)
What was the first spring system used?
The first spring powered-clocks appeared in that century and evolved into the first large watches by the 16th century. In 1676 British physicist Robert Hooke postulated Hooke’s law, which states that the force a spring exerts is proportional to its extension.
How many types of spring are there?
Different types of springs: compression, extension, torsion, & constant force springs.
