i am taking a +/-5 voltage signal is supposed coming from a torque sensor. this is supposed to be equal to 100 N*m. However, -5.04 volts is actually equal to 100 N*m and 4.85 volts is actually equal to 100 N*m. I need to scale this signal to a maximum input of 200 mV for display on a panel...

i am working with an encoder that says its output is impulse(ttl). I'm not quite sure what this means. is it just a digital signal? how does it work? any help you can give me would be great.

I am building a test stand that will implement 7 different panel meters. These panels are for torque, angular position, and voltage. Could anyone recommend affordable panel meters that will work for this application. Any help would be great. Thanks

sorry, i should have said this before, but the resistance needs to be able to vary from no resistance to around 7 N*m

the purpose of the motor is to apply a small resistance (4-7 N*m) to the steering wheel shaft. The shaft itself will be turned by a steering wheel. this should allow the motor to run as a generator creating a voltage.

I am trying to implement an electric motor as a generator at the end of a steering wheel shaft. The motor would be used to apply a resistance torque to the shaft. What type of motor would you recommend?

basically i want a meter that will show a signal similar to the way an oscilloscope would, with time on the x-axis and the output on the other. I don't think it really needs to show the actual angle as the output on an angle sensor would be voltage and that would correspond to an angle, i think...

Is there any kind of signal meter that can take an analog output of rotational velocity, angle etc. and show it in its full form. If there is meters like this could you recommend a few? Thanks

thanks for your help

There are two point charges q1 located at (4,0,-3) and q2 at (2,0,1) if q2=4nC find q1 such that the force on a test charge at (5,0,6) has no x-component. I think I would know how to do this problem if I knew what a test charge was. Is it just one electron.

ok, thanks

i have a force field F = 2xy*(ux)+(x^2-z^2)(uy)-3xz^2(uz) where ux,uy,and uz are unit vectors in the direction indicated. I have to find the work done by the field on a particle that travels from A(0,0,0) to B(2,1,3) on a straight line. work is regarded as the integral from A to B of the dot...

at point T(2,3,-4) in rectangular coordinate system, how would I express the Z unit vector in the spherical system and the R unit vector in the rectangular system? I know T in spherical coordinates is (5.385,-42 degrees,56.3 degrees) but i have no idea how i would express a unit vector in a...

i have a vector h whose value is 3ax+5ay-8az where a is the unit vector in the direction beside it, how would i find the angle between this vector and the x,y,and z axes

I have a picture i need to open. Its file extension is .img. How can I open this so I can attach it to Microsoft Word?
