AI Thread Summary
The discussion focuses on gathering information about tennis and volleyball throwing machines, with an emphasis on constructing a volleyball machine. Participants suggest researching simple machines like trebuchets for inspiration. A key concern raised is how to achieve velocity control for the motor used in the machine. The conversation highlights the need for specific ideas on maintaining ball trajectory and minimizing rotation. Overall, the thread serves as a resource for those interested in building ball-throwing machines.

I wonder that are there anyone who have an idea about ball throwing machines(tennis ball throwing machine, volleyball throwing machine etc.) How can i get information about this subject?
(i am sorry of my bad english, i wish i could explain what i want to learn :smile: )

These things?

Are you trying to figure out how to make one?

thank you for your help.
yes i was trying to figure out that.
i am trying to project a volleyball throwing machine and getting knowledges about that. i need any different ideas. the two thing is to keep in mind that the ball will not rotate on its own center as much as possible and the trajectory is determined (specified)
 
Not sure if you are trying to construct something for yourself or manufacture something, but if you are looking to make a simple ball hurling machine, do a Google search for Trebuchet. It is a simple style machine that you could use to hurl any type of object.
 
thank you everyone who helped me, i get many informations about the machine. i have only one problem that;
how can i do velocity control to a motor, in other words, by using what kind of motor, i can control the velocity of the motor?
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
