Ultrasonic Standing Wave Suspension could the transducer support itself?

AI Thread Summary
The discussion centers on the feasibility of using ultrasonic standing wave suspension to allow a transducer to support itself. It references Hemsel's 2013 findings, which indicate that a surface area of 1m2 can support 11.5 kN at 16 Watts. The key question is whether the transducer can suspend itself from the reflector, considering the suspension point is at the second wave. Calculations suggest that to lift a weight of 1.15 metric tons, approximately 5 kW of power would be required, factoring in potential losses. The conversation highlights the complexities of scaling up the technology while maintaining efficiency.

Ultrasonic Standing Wave Suspension could the transducer support itself?

Essentially looking at items that state a surface area of 1m2 could support 11.5kn at 16 Watts (Hemsel, 2013) could the transducer suspend itself from the reflector using the same theory even though the suspension point is at the second wave from the transducer if it were within the parameters of weight to surface area?

I fear you overlooked something.
They state clearly : "The first system was able to lift a weight of 3 kg using an electrical input power of only 16 W. Based on the surface area, a lift capacity of 11.5 kN/m2 was reached."
11500/30 ~ 380; 16W* 380 ~ 6000W, so even assuming peripheral losses will diminish when you scale up, 5kW seems to be a more reasonable estimate of the power required to lift 1.15 (metric) tons, given the technology used.
 

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
