Yes I should have mentioned this earlier, the acceleration starts in the interval before X1. I didnt include it because it is impossible to know its real angle and is therefore null data. Does this effect what you have replied with so far?
I will give this (above quoted) a go for sure.
In you reply you say that the 1.6 micro-second interval " assuming a uniform velocity within that timescale is not a good approximation." are you saying I am working with "bad" data? If so does this mean that i try your solution, or any solution...
I need help! Could you please double checking my work: calculating a Power information from data I am collecting. I have been Googling and wiki'ing for weeks now and I think I have it right but I need someone to confirm or correct what i have done..
The graph data comes from and Optical Rotary...
Can you please tell me what MS Excel uses to find a Power trendline?
I have been experiment with data from my PunchBot project and it seems the Power Trendline fits the best. The plan is the used the data from my machine (an array of time intervals) to find the curve of the acceleration and...
Firstly, I am sorry for what is likely stupidly simple question however I can't find a helpful answer in Google so I must be missing obvious.
Can you determine the initial force that moved an object by knowing only its current velocity and weight?
So if a 1kg object is moving through space...
Ahh see that makes sence. I was see "kg m2" and I was thinking what does surface area have to do with it? :)
Thanks for you help mfb, that has me pointed in the right direction.
I had consider an accelerometer but I decided against it because they get increasingly noisy the higher the G figure you want to read from them. Obviously the g reading is relative to the weight of the punching bag but by my approximate calculations you would need a 5-10g+ bag to bring the...
I googled "moment of inertia" and (correct me if I am wrong) it looks like I should to calculated each part (axis, rod, head/pag) of the swing arm construction and add them all up to arrive and mass figure?
I am building a machine for my martial arts club so that I can have a bit of fun and measure the speed and reaction times of my club mates.
The design that I feel would yield the most reliable and accurate results would be to mount an upside down 'pendulum' on a frame. At the head of the...
