AI Thread Summary
To calculate torque versus crank angle for a Wankel engine, determining the pressure values p1, p2, and p3 is crucial. The application of the PV diagram for an ideal cycle may not directly apply to a Wankel rotary engine due to its unique design. While the four strokes are conceptually similar to those in a piston engine, the three-chambered rotary engine requires specific assumptions that differ significantly. Accurate pressure values can be derived from experimental data or simulations tailored to the Wankel engine's characteristics. Understanding these nuances is essential for effective torque calculations in this type of engine.

i want to calculate the torque vs crank angle for wankel engine...however i get stuck on entering the pressure value which is p1,p2,p3...how can i determine the pressure value?

You might have a problem applying the PV diagram for an ideal cycle to a wankel rotary. Although the 4 'strokes' are the same and are governed by the same rules, the 3 chambered rotary will require assumtions that deviate quite a long way from a piston engine.

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

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...
