AI Thread Summary
For a bicycle workstand project involving a ratchet and pawl mechanism, the solenoid's strength is crucial for effectively locking the pawl. The linked solenoid provides a push force of 150 grams with a 5mm stroke, which may not be sufficient for a 12.1kg bike. It's important to calculate the required force based on the design specifications to ensure proper functionality. Understanding the differences between solenoid types—linear, rotary, tubular, C-frame, and D-frame—can also aid in selecting the right component. Determining the necessary current for locking the ratchet will depend on the specific force requirements and solenoid specifications.

I am doing A2 Level Product Design (as well as Physics obviously ) and I am making a workstand for a bicycle. It involves a ratchet and pawl mechanism which will be locked out by a solenoid acting on the pawl.

The bike weighs roughly 12.1kg and the ratchet wheel from nylon. The pawl is aluminium and will be pushed into the ratchet by the slug protruding from the solenoid.

I do not have any idea as to whether this solenoid will be strong enough, so please could someone let me know if it is?

If not, is there any particular size I should be looking for? Also, can anyone explain the difference between the difference between linear, rotary, tubular, c frame and d frame solenoids? One last question, how do I determine the current needed to lock the ratchet in place.

If any of those questions could be answered I would greatly appreciate it.

Many thanks,

Dom.

I don't really understand your application, but solenoids are rated to provide a certain push / pull force. Do a little calc and figure out what you need. The one you linked to, for example, provides 150 gram force with a 5mm stroke.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

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 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
