Ok, Basically what I'm getting at is the structure of a striking object to yield it's energy to a target.
Then the overhand right is thrown, at the point of impact, the structure that you have created cannot yield more foot pounds of energy to a target than the structure that you create with a straight right hand.
IF you were going to strike a flat wall at any angle you chose would you want to be in front of it with a straight right or would you arc your arm out and do a looping punch? When you push something like say...your car breaks down. Are you going to get behind it and push Straight or are you going to get to the side and push at an angle to get it to move? A push is not a punch I KNOW this...but the *principle* is the same as far as what yields the greater power.
The Cross is NOT a more structurally sound punch than a hook. You are "crossing" the strength of the frame...whereas a hook is slightly more powerful because of the kinetic energy yielded to the target due to the framework of the punch. The hook knocks more people out not necessarily because of the power but because of the angle you are striking the head (getting it to rotate, which causes the shock needed to KO).
One last thing and a fairly important note: when you throw a punch with an arc such as the Overhand Right ...upon impact due to the framing you have created with the punch...more energy is lost due to the inability of the structure of the punch (the shoulder, elbow etc..) to not "cushion" or absorb some of the power (i.e. your arm will bend slightly, your shoulder will give slightly ...now this is true with any punch but the greater the arc away from the body, the weaker the structure and less energy transference will occur. (i.e. hooks are tight punches held close to the body and not wide arcing punches....why? because there's no power in a long wide hook!!!!)
However, the Straight Right Punch yields more raw power to a target than the Overhand Right. This does not mean it will knock more people out or that it's a better punch in certain situations. It is however, a much stronger punch for the amount of power it yields.
I am a Sambo stylist that also practices Boxing and Thai-boxing. Overhand rights are OFTEN thrown in Sambo, lots of looping punches. They are good punches for the right situation and I disagree with the boxing poster that says it's a "sloppy" punch. It's not any more sloppy thank the hook punch and it does require skill to throw correctly.
I'm also a physical therapist so I know a little about what I'm speaking of when it comes to body structure
With that logic left or right hooks would be less powerful than a right cross.
If the rotation is the same then all objects connected to the body will rotate accordingly.
