I just wanted to ask another question in regards to that post you made. Does the weight of a person directly play a factor in the acceleration of the head when absorbing punches? If yes, how so? Does sufficient energy get transferred to the body in order to help absorb punches better?
If most...
Are there any scientific evidence suggesting that athletes decline in athletic performance/abilities after reaching their late 30s?
Such as in terms of speed, agility, reflexes, hand eye coordination, stamina and etc.
If yes, what are they?
Yes, you'd be correct! Perhaps knitting wasn't the best example. However, my point was comparing hand eye coordination in an activity that requires a response to an external stimuli (catching a ball) vs hand eye coordination in any activity not requiring a response to an external stimuli (sewing...
So what would you say is the difference in hand eye coordination when reacting to something (catching a ball) and when not reacting to something (sewing or knitting)? What are the different events that occur in the brain / body (hand & eye) during those two different activities requiring hand...
I'm referring to image processing, such as a robot having image processed by its control unit when 'seeing' things through its eyes / visual system (such as through cameras).
What are the factors which determines how many bytes / kilobytes / gigabytes of data a computer can process every second? Are there any equations / formula / rules that can be used to work this out.
In an electric motor, there exists two magnetic fields where usually one of them is a permanent magnet whilst the other is an electromagnet. However, how does the magnetic fields enable the armature to rotate / spin?
Also, how is the torque from the rotation of the armature transmitted to drive...
What are the differences between hand eye coordination and reflexes?
So when one catches a ball, they must have a specific level of hand eye coordination and reflex / reactions in order to be able to catch the ball. What aspect of catching a ball is related to hand eye coordination and what...
1) What is friction loss / are friction losses?
2) How can it be determined / measured / calculated / figured out?
3) How does it affect the power output (force * speed) of an electric motor when an electric motor is moving / lifting objects? Why does it have such affects?
Would you be able to provide an explanation and an example of how rack and pinion can be used in a robotic / exoskeleton arm to convert rotary motion of an electric motor into linear motion when lifting / moving objects linearly with the arm / hand? How / where would the rack and pinion be...
