Playing tug creates problems, where do people get this idea?

Question by UHave2BeKiddingMe: Playing tug creates problems, where do people get this idea?
Where in the world do people get this idea?

This morning we had some “gems” of responses from someone who wanted to try to get their dog to play tug.

One response
“It creates problems in dog’s training.”
“That’s not a very nice game it will change your dog’s behavior! He will always bite and stuff and destroy things!”

Every top performance trainer I know and work with uses tug to build drive.

My agility instructor was so excited upon meeting what was my new puppy to see how strong his tug was at just 16 weeks and encouraged me to work and develop it stronger.

I wish my other two dogs would tug, it would really make a difference in our agility training.

Nearly every drug/bomb/search dog is trained with a tug and that is their reward for getting the job done.

Is this just some fallacy the younger generation has been taught and instead of research they just repeat?

For those who have trained dogs to performance titles do you encourage your dogs toy/tug drive?

For those that say its bad to encourage with your dog, where in the world did you get that information?
CHIX- I someone who does BOTH, patrol dogs and detection dogs and the tug is the preferable reward of choice because it allows a dog to express drive in a way that is very satisfying.

So although I did not say ALL detection dogs were trained that way, I said nearly all, that is those that are trained by people who know what they are doing.

People get this idea from dingbat trainers at Petsmart! Anyone that knows anything about training a dog knows that prey drive is something you NEED to have in a dog in order to do more intense training. Dogs with a high prey drive excel at training and focus, and that’s why k-9 police dogs are often rewarded with a game of tug. The idea that tug will cause aggression in dogs comes from the all positive trainers. Many people associate prey drive in dogs as a bad thing or even aggression, because of this people assume you need to train it out of your dog.

3 physics problems!? CHALLENGE?

Question by mathstinks: 3 physics problems!? CHALLENGE?
1. to simulate the apparent weightlessness of space orbit, astronauts are trained in the hold of a cargo aircraft that is accelerating downward at g. Why will they appear to be weightless as measured by standing on a bathroom scale, in this accelerated frame of referenc? is there any diff between their apparent weightlessness in orbit and in the aircraft?
2. a cartoon shows the toupee coming off the head of an elevator passenger when the elevator rapidly stops an upward ride. can this really happen without the person being tied to the floor of the elevator? explain.
3. calculate the maximum acceleration of a car that is heading up a 4 degree slope (with the horizontal) under the road condition of rubber on dry concrete (mu = 1) assume that only half the weight of the car is supported by the two drive wheels and that the static coefficient of friction (1) is involved (tires aren’t allowed to slip during acceleration)

PLEASE HELP!!!!!!!! please!!

1. When you are in a vehicle accelerating downwards at g, and you are accelerating also downwards at g due your mass or weight, there is no interaction between you and the vehicle, that’s why the scale shows you’re weightless.
It is not quite the same as you’re in orbit or space, in orbit the gravity force is balanced by the centrifugal force due to the orbital movement, and in space there is practically no gravity.
2. When you move up at a certain speed , and suddenly elevator is stopped you still have same the speed at that very moment, this meant you are lifted from elevator’s floor until the gravitational force stop your move and brings you back to the elevator’s floor. In real life this won’t happen because speed is relatively slow and there is no chance to stop elevator suddenly (speed=0)
3. The normal force to the street from drive wheels = 0.5 * mg * cos 4
then static friction force max = mu * 0.5 * mg cos 4 = 1 * 0.5 * mg * 0.998 = 0.4988 mg
0.4988 mg = m*a
a = 0.4988 *9.81 = 4.893 m/sec**2

Do you have problems with your HO trains falling off the track?

Question by Mental: Do you have problems with your HO trains falling off the track?
What is the next larger model scale trains?

Best answer:

Answer by Whit W
All scales of trains can have problems staying on the track. Most of the time the problem is wheels out alignment and track problems. NMRA makes a device for checking wheel guage, switch points, etc. It can quickly help you find problems with your track and cars. Talgo trucks are notorious for derailing while running in reverse and through switches and compound curves. Athern and other makers make cars with body mounted couplers which run much better. Switches are a major cause of derailments in any scale including 1/1. Check for debris in the frogs and proper alignment with adjoining track. A good rule of thumb is not to connect a switch to a curved section but to have a short straight approach. In Ho and N scale, sometimes track connectors will come loose and cause track to separate or become misaligned. Connectors sometimes when being joined, end up under the rail which can cause height problems and derailments.
Many cars that come with sets have problems about being under weight. More weight will help in some cases as well as swapping out plastic wheels for steel wheels.
Also slower operation speeds can prevent some problems as well as look more realistic.
If you want to abandon HO scale the next scale up is O scale which is about twice the size. You can get On30 equipment that will run on the Ho track you already have, This is narrow guage O scale equipment that is running on track that is 30 scale inches wide. The next scale up from O is G scale which is very forgiving as far as staying on the track. I install these in resturants and these can run for months with out any attention. I have investigated a few derailments that customers have had and I’ve never had one that was a track issue. It’s usually contact with foreign objects like escaped ballons that trains tangle in the strings.

Model railroading problems any suggestions?

Question by anonymous: Model railroading problems any suggestions?
I am new to model railroading and put a DCC controller on a DC layout(stupid me)and nothing worked even my DCC locos, so i took it off and put the DC controller back on and then my DC locos were making weird sounds when running and my DCC locos that worked before dont work at all.
Any ideas?

Answer by dtwarwick
Well, I’m not familiar with these controllers you describe, so this is a guess. I do have a Master’s in Electrical engineering though, so it’s not a completely uneducated guess. My guess is that the ‘DCC’ controller outputs a different voltage or power pattern (probably higher), and that you’ve blown components in your engines. You may be lucky and these components are just fuses or diodes. Or you may have burnt out motors.

I’d recommend you find out what voltage your engines are supposed to run on, get yourself a standard transformer rated for that current or higher, and test your engines independently. Once you’ve ruled out which ones are damaged and which ones aren’t, you can sort out what damage may have been done to the controller. It’s also possible your controller is rated for the total load you’re putting on it. If that’s the case, just reducing to a single engine and adding one at a time can help you find the upper limit.

With more information about the controllers & engines (Voltage & current ratings), more specific help might be offered.
