    What Are the Key Factors Influencing Current and Resistance in DC Circuits?

    However that doesn't take away that chRoot was misleading: I will state it again. Just by him saying that by putting a circuit in series or parallel doesn't mean anything to the total circuit resistance without taking into context the resitances of each branch. Omh's law states nothing...

    What Are the Key Factors Influencing Current and Resistance in DC Circuits?

    Very funny. The math is right the wording is wrong. At least I admit that I am wrong. Funny no one will stand up to an Admin. I am sure he doesn't mind being corrected. This is a professional forum of adults. Constructive critisim is what this forum is all about.

    Derive Linear and Angular Acceleration from A Force and a Point of application

    Thank everyone for the replies. The clearest answer I was looking for was that force affects a ridgid body regardless of the point of application. Thank you to baffledMatt and TALewis! Yes it is quite a simple problem indeed. Really all one has to do for this rigid body is calculate...

    Derive Linear and Angular Acceleration from A Force and a Point of application

    What is really interesting is that I have not found a single shred of information on the internet that covers explicitly what I have done here. Calculating torque finds the proper amount of torque based on the distance from the axis of rotation. It should be no different for a free body with...

    Derive Linear and Angular Acceleration from A Force and a Point of application

    Hmmm I could have sworn I explicitly stated exact details in my original problem. In order for you to apply force in a 3D simulation you must "pick a point". It is not enough to know the direction and magnitude of the force being applied. The point P' doesn't "move" its merely a position...

    Derive Linear and Angular Acceleration from A Force and a Point of application

    To expand to the 3D environment I created a vector from the center of mass to the point of impact. I then took the inner product (dot product) of these and used that as a scale factor in the linear force.

    Derive Linear and Angular Acceleration from A Force and a Point of application

    Progress, Perhaps. I have derived a formula for solving this. Based on my guesswork of how a free-body in the described environment would work. [1-(r-d/r)]F' = L' (1) Such that L' is the new scaled Force that takes into consideration how far away it...

    Derive Linear and Angular Acceleration from A Force and a Point of application

    Setting the Stage: A uniform sphere has a mass of 100 kilograms and a radius of 10 meters. It is located at [0,0,0] It is in static equilibrium. We are in constant time. We are in a vacuum, there is no gravity, friction, or any other forces to act upon our sphere. We are using a...

    What Are the Key Factors Influencing Current and Resistance in DC Circuits?

    Total Circuit Resistance Rt Total circuit resistance in a DC circuit is irrelevant of any combination or groupings of series, parallel, or complex series-parallel branches. Rather, it is the actual total resistance of the circuit that determines the total resistance. That sounds very blunt...
