AI Thread Summary
To calculate torque for an electric go-kart motor, the motor's specifications, including RPM, output watts, and gear reduction ratio, are essential. With a motor output of 425 watts and a gear reduction ratio of 10:1, the achievable torque can be determined using the formula: Torque = (Power / RPM) * 5252. However, reaching a speed of 60 km/h in 10 seconds would require approximately three times the current power output, indicating that the existing setup may not suffice for the desired acceleration. Utilizing simulation tools and studying related theories can provide further insights into optimizing performance.

I am building an electric go kart , and I'm just trying to get my initial justifications correct, with respect to the classical physics involved.
SPECS: motor rpm 1600
: motor output watts 425
:gear reduction ratio 10:1
. The Motor i have has a max RPM of 1600, an anyone show me best how to perform these calculations ? i understand that i need acceleration if that is the case can i just say i would like the car to accelerate to 60km/h in 10 seconds. please provide me the best specification with above details,

Although an electric motor can often produce more power for a short period of time, you will probably no be able to reach 60 km/h with 425 W. You would require about 3 times that power to reach 60 km/h in 10 s. Play around with this simulator and read the theory about it to learn more.

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...
