Hello,
Presently i am working on a project to generate angular acceleration on a cylinder. The cylinder has silicone gel material in which we have markers to track to understand the respective dispalacements and strains in the material by applying this angular acceleration.
I already have a fixture that can generate linear accelration, the details of the set up are as follows. I want to modify make additions to this set up to generate angular acceleration.
Pendulum : The rod of the pendulum is around 65 inches tall. One end of the rod is free to rotate whereas the other end has a pendulum where i can add and remove weights. Also i can change the angle of the rod of pendulum to attain angles from 0 degrees to 85 degrees. This was designed in such a way to attain maximum rotational kinetic energy conveyed to the sled to gain maximum linear accelerations.
Sled : Sled which moves on rails has a cylinder on which i will be measuring the angular acceleration. For angular measurements i will have the sled contrained not move on rails. At this point i am not sure about the diameter of the cylinder but i assume it would be approximately 12 inches.
My question was how do i convert the rotational kinetic energy of the pendulum into angular acceleration of the cylinder.
I appreciate your guidance and wil provide more information if required. Please let me know.
Thanks
