    Newtons Wheel
AI Thread Summary
To calculate the necessary Newtons to turn a 1m wheel with a 1kg mass and 1cm width, one must consider the desired angular velocity and the time required to reach it. The force applied at the outer circumference will determine the torque, influencing the wheel's acceleration. Without friction, the amount of force can vary, affecting only the angular acceleration. A specific answer requires defining both the target angular velocity and the time frame for achieving it. Therefore, the calculation is contingent on these parameters.

How much Newtons is needed to turn a wheel with radius 1 meter and mass of one kilogram and width of 1cm, exerting force on the outer circumference of the wheel and assuming no friction occurs?

You can use any amount of force you want. The only thing that will change is the angular acceleration. The smaller the tangential force, the smaller the torque, and hence the more time it will take to accelerate up to any given rotational speed.

In other words, to get a unique answer to your question, you must specify

- what angular velocity you want to reach
- how much time you want it to take to reach that angular velocity
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
