AI Thread Summary
Brake power in internal combustion (IC) engines is calculated using the formula hp = [RPM * Torque (ft-lbf)]/5252. The discussion clarifies that brake horsepower (BHP) refers to the engine's output power, while some participants inquire whether the focus is on brake horsepower or braking forces from engine compression. Additionally, there is a distinction between real and theoretical engines in the context of the calculation. Understanding these nuances is essential for accurate calculations of engine performance. The conversation emphasizes the importance of clarity in terminology when discussing brake power.
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...
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
which motor is reasonable for slider crank motion , where the motion of slider should be control with motor speed.
Thank you
