hi. if I understand you told me Ixyz . Fxyz = 0 in order to find a colinear vector. ??

yes I call I the Position vector.. in your case r .. the 2 arethe same..

yes. if you see I try this is in "The attempt at a solution" but its not possible fin Ix, Iy and Iz

Homework Statement Hello everyone :smile: I have got a cylindrical 6 axis force sensor (so I have the force Fx, Fy,Fz and torque Tx, Ty, Tz). Using these data I don’t know how I can find the point of force application. Homework Equations The Attempt at a Solution I try this...

Homework Statement If we only know the force Fr, Find the angular velocity of the flywheel. Homework Equations The Attempt at a Solution in the pulleys F=F1=F2=F3 Fr=(F Sin β)/sin (β/2)=2F cos (β/2) F = (2 cos (β/2))/Fr so now for the flywheel I=1/2 MR2 ...

ok, thanks for all your ideas.. the work is for a bio-mechanics project.. so I try to do something good.. thanks for your help, I work .. and I will come back bye

HI Really thanks for your help..

hi.. "I like serena" I'm trying to write the physics equations in kayaking.. this is all my problem... so, the propulsive force have the same valuer that the horizontal force in the center of mass of the paddle buts its negative?? thanks so much.. one more time.. :biggrin: have a...

Homework Statement hello,:smile: I don't understand what is the propulsive force and how I can develop this equation? apply to kayak What is the propulsive force?? Which is the propulsive force in kayak?? generate for the paddle thanks for hour help:wink: Homework Equations...

yes, you are in time.. for save the science thanks again and have a nice day =)

I'm sorry, I found the same equation in two scientific paper, and we are wrong, http://www.worldacademicunion.com/jo...o03paper01.pdf you have 5 more minutes for help me ?? thanks again

Oki doki.. :redface: thanks so much I'm sorry, I found the same equation in two scientific paper, and we are wrong, http://www.worldacademicunion.com/journal/SSCI/sscivol03no03paper01.pdf you have 5 more minutes for help me thanks again

thanks so much for your help, :smile: "I like Serena " :smile: I'm really sorry, but i can't find the same answer: for the right side of the equation =(mboat dVboat/dt ) + (MT−mboat)((dVcrew/dt + dVboat/dt)) =MT(dVcrew/dt + dVboat/dt) - mboat dVcrew/dt could you tell, please where...

Hi, I cannot find the answer (Copy and paste)Book; According to Newton’s second law, a linear force, F, generated by a system can be given by ƩF=ma (1) where m is the mass of the system and a is its acceleration. If input forces and masses of a system are known, then the velocity, V, of that...

Homework Statement What is the equation of motion of canoe stroke in canoeing sport Homework Equations F=ma Momentum=mV The Attempt at a Solution My P - DT = MT (dVcrew/dt + dVboat/dt) the Book response, P - DT = (m dVboat/dt ) + MT (dVcrew/dt + dVboat/dt)...
