Can't tell if there is a groove in the middle, but I'm going to say no. That's a Herringbone gear, a special type of double helical gear.

You wish to raise one side of a 5,000 kg car to change a flat tire. You have a strong 2x4 to use as a lever, and a 15 cm high block for a fulcrum. The fulcrum is 304,000 µm from the load, and the lever is 1.52 × 10^-6 Mm long. How much force is needed to lift the car? Give your answer in kg.MadCow2357 wrote: ↑September 7th, 2019, 10:28 am Someone else go for me I can't think of a question lol

Before solving, I just want to note that force is measured in Newtons, so I'll give my answer in both kilograms and Newtons .Things2do wrote: ↑September 7th, 2019, 9:05 pm You wish to raise one side of a 5,000 kg car to change a flat tire.

Assume that the jack point is in the middle of the side, and that you need to lift half of the car's mass.
Sorry if that's not allowed by the rules or is overly complicated. I ain't read the rules that closely yet.
Hint: Notall of the values given are needed. It should be a simple formula.
The kg/N thing was my error... I wanted the answer in Newtons.Justin72835 wrote: ↑September 8th, 2019, 9:11 pmBefore solving, I just want to note that force is measured in Newtons, so I'll give my answer in both kilograms and Newtons :D.Things2do wrote: ↑September 7th, 2019, 9:05 pm You wish to raise one side of a 5,000 kg car to change a flat tire.

1250 kg or 12250 N
