    Degrees Motor
AI Thread Summary
A user is seeking advice on a motor that can rotate a piece of metal 90 degrees using a simple switch. The discussion highlights the need for a mechanism to stop the motor after the rotation, suggesting the use of limit switches. A servo motor is recommended for precise control, along with a gear system to facilitate the movement. Additionally, a two-way switch can be employed to reverse the direction of the motor. Overall, the conversation emphasizes the importance of additional components for effective operation.

Hi everyone, learning a bit of hands on engineering and have no idea what to search in order to buy what is needed. I am looking for a motor that can be activated by a simple switch on a wire that will rotate a piece of metal 90 . degrees. Excuse the poor image but hopefully someone can point me in right direction for this project.

You are going to need more than just a switch and a motor, I think. The switch can tell the motor to turn but you have to have something to tell the motor to stop turning. How about the reverse? Do you want the piece to be able to rotate back to its original position?
 
Yeah basically to throw a switch that will move it 90 degrees one way and then flip it the other direction to move it 90 degrees back to the original starting position. Is there anything premade that might work for this?

Doesn't sound like anything I've ever heard of but just 'cause I don't know doesn't mean it doesn't exist.

Have you considered using a servo motor?
 
If the rods are hinged attach a large gear to one of them parallel to the horizontal i.e. like a hand grinder with 2 handles. Then connect a simple DC motor to it via a smaller gear. Use a 2 way switch to operate the motor.

If you need stops use limit switches and a few more wires
 
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...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
