Tape experiment how to pull at constant speed?

AI Thread Summary
To conduct a physics experiment on the peeling force of tape at a constant speed, it's suggested to use a weight falling vertically attached to a string, which can maintain a consistent force. The initial attempt to use a motor was ineffective due to insufficient strength. It’s noted that using a spring is not advisable, as the force varies with the spring's stretch. Maintaining a constant force is key to achieving a constant peeling velocity. This approach will allow for accurate measurements of the peeling force in relation to peeling velocity and angle.

hi all
i'm a high school student doing a physics experiment about the peeling force of a tape.
I want to see the realtionship between the peeling force and the peeling velocity but I cannot think of a good way to pull at constant speed.
I tried to connect the spring to a motor so that the motor would pull the spring at a constant speed but the motor is not strong enough.

how can I pull at a constant velocity and measure the force with the peeling angle and all other things kept constant?

please help me! :D

Probably, you will get a constant velocity if you pull with a constant force.

One way to do that is have a weight falling vertically, attached to a string that applies the force to the rest of the experiment.

Using a spring is a bad idea, because the force will change depending on how much the spring is stretched.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
