    Shaft Torque
AI Thread Summary
The discussion focuses on calculating the torque on a shaft when lifting a 1000 kg load with a winch at a wire speed of 35 meters per minute. Participants reference the formulas T = Fr for torque and P = Fv for power, emphasizing the need to determine force (F), velocity (v), and radius (r) for accurate calculations. The required horsepower for the electric motor, operating at 980 RPM with a 70:1 gearbox ratio, is also a key point of inquiry. Users are encouraged to engage actively and adhere to forum rules for effective problem-solving. Understanding these calculations is essential for proper winch operation and motor selection.

What is the torque on a shaft when applying a load of 1000 kgs. through winch lifting at a speed of 35 meters per minute wire speed. What should be the H.P of an electric motor if it runs the winch. The motor rpm is 980. Gear box speed ratio is 70:1.

PF expects users to put in some effort, check out the forum rules.

Are you familiar with T =Fr ?
Or an answer can be had more directly via:
P=Fv
 
What is F, v and r in the formula. I am not familiar.
 
Force, velocity and radius.
 
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...
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
