What are four examples of properties?

What are four examples of properties? physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples. Can you identify a substance by its density? You can identify an unknown substance […]

How do I increase damping in my system?

How do I increase damping in my system? Therefore, a means of increasing ‘effective’ damping to the system is needed. To increase damping, rotating machinery designers are using fluid films or compliant materials between bearings and ground. To make the damping ‘effective’, it may be necessary to allow for additional motion by softening the bearing […]

What happens to the mass of water when frozen?

What happens to the mass of water when frozen? Water molecules, when they freeze, tend to stick together in a hexagonal form. That’s why when water freezes, it expands. Same mass but with greater volume means that ice is less dense than liquid water. It’s also why ice floats to the surface in a glass […]

Why are there no circular orbits?

Why are there no circular orbits? Why not circular? Orbits are eliptical because of Newtons Law of Gravity (bodies attract each other in proportion to their mass and inversly proportional to the square of the distance between them). All worked out by Kepler some years ago. A circular orbit is a special (and very unlikely) […]
