Why is moment of inertia of a solid disc smaller than that of a ring?
Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.
What is moment of inertia of solid sphere about its diameter?
Rotated about a line on the surface ? I = Mass * radius2 . Rotated about a line through the centre : I = (2 * mass * radius2) / 5
Is bike a solid?
a bicycle tire is a solid, because it is made out of rubber and rubber is solid. so, therefore, a bicycle tire is a soid.
The moment of inertia of a solid cylinder is?
the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.
How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
Why is hollow steel pipe stronger than solid steel?
For a given outer diameter, the solid shaft is stronger, but it weighs more.For a given weight, the hollow shaft is stronger because it has a bigger diameter.due to less weight & less bending moment..............the resultant bending moment for a solid pipe is much larger than for a hollow one because of their weight difference
What is the Moment of inertia of a solid hemisphere?
2/5 mr2
Which one would compress more a solid rubber bicycle or a inflated mountain bike tire?
A "solid rubber bicycle" wouldn't be particularly useful, so I assume that you actually mean a comparison between a solid and an inflated bicycle tire. Answer: It depends. An inflated tire of a very high pressure will compress less than a solid tyre made out of soft rubber. OTOH a hard rubber solid tyre will compress less than a low-pressure inflatable tyre.
How did the boneshaker bicycle get its name?
The wheels were solid, no tires and tubes on those babies.
If all people move to the equator how would it affect Earth's rotational inertia?
The mass of the gasses that make up our atmosphere weigh much more than the human population (1 trillionth of the earths mass) and move opportunistically into dense and low density pockets in all positions at all times on the globe and they have absolutely no effect on the rotational inertia. Consider the earth is not a solid mass inside or out, it is basically a hydraulic dampener. Now if you could generate sufficient vibration waves in order to harmonically disrupt the fluid dampening effect it would be possible for the system to fault and the earth to throw a bulge.
Why bicycle is not flywheel?
A flywheel is (usually) a heavy, solid chunk of spinning metal that is used to store rotational energy. Combustion engines have them to make them run smoother at low revs. W/o a flywheel the power from the engine would be delivered in sharp pulses, making for a jerky ride and maybe stalling the engine. For a bicycle you don't want the added weight of the flywheel, and the human as engine does a good job of smoothing out the power anyhow. If you insist on pushing the comparison you can perhaps claim that the wheels on the bicycle will act as flywheels when the bike is at speed.
Are the particles in solid motionless?
No. The particles in a solid are not motionless. They have different types of motion, such as vibrational, rotational, etc. But they do move, just not as easily or as readily as they do in a liquid or a gas.
