Ever weigh your chains?

[Definitive Dave]

My own chains are heavy until other guys fix them for me.
I try not to spout opinions on stuff I don't know first hand.
I don't take criticism personally.
I try to learn something everyday.
I think secrets are evil, but realize we cant give our pin number to strangers so...
I probably see the best in people because that's what I look for.
I try not to pick fights that I don't care if I win.
I lose my train of thought before I finish typing a post

Now I think I get it. The equivalent to unsprung weight.

 

[Definitive Dave]

nah nah I think it more about the judicious removal of weight than the total
<warning engaging talking out my ass> I doubt the weight savings increases chain speed much, which would be easy to actually test with out of the wood, same power head, bar, and tune, but the effects of making the chain faster by 40% or more create a lighter chain as a byproduct of all the work done <ass flapping disengaged>
Anybody have access to a cheap bulk of titanium sheeting? I have a theory

Do the laws of Newton have anything to do with this ? If you drop a heavy and a lightened chain off the empire state building will one hit first or both at the same time ?
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

This law is often called
"the law of inertia".
What does this mean?

This means that there is a natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion.
Let's study the "skater" to understand this a little better.

What is the motion in this picture?

What is the unbalanced force in this picture?

What happened to the skater in this picture?
This law is the same reason why you should always wear your seatbelt.

Now that you understand
Newton's First Law of Motion,
let's go on to his Second Law of Motion.

 

[junkman]

According to Newton's second law...
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
What does this mean?

Everyone unconsiously knows the Second Law. Everyone knows that heavier objects require more force to move the same distance as lighter objects.

However, the Second Law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematical equation:

or
FORCE = MASS times ACCELERATION



This is an example of how Newton's Second Law works:

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car.

Answer = 50 newtons


This is easy, let's go on to
Newton's Third Law of Motion

 

[junkman]

According to Newton's third law...
For every action there is an equal and opposite re-action.



What does this mean?
This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.



Let's study how a rocket works to understand
Newton's Third Law.

The rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force.


UP,
UP,
and
AWAY!






You have just learned about
Newton's Three Laws of Motion.

I didn't see no chainsaws in them diagrams.
If I attach a rocket to a properly sharpened saw tooth cutter it should either tear the tooth off of the chain or jerk the saw out of my hands, in either case I'm gonna lose some chest hair

Chainsaws were not invented yet when Newton was alive .........Jeesh

 

[Fish]

What if your saw is Snellerized? And the chain speeds approach the speed of light?
Would that be "relative" to the discussion?

 

[SawTroll]

Inertia and momentum is relevant - no doubt about that. What complicates it is that there are other forces in play as well.
