What's is the formula to find the force(torque) to throw a mass in the air that is 500kg/m(3) with 2 pulley and a belt.

Thanks

There is not a single formula, but a collection of formulas. See https://en.wikipedia.org/wiki/Equations_of_motion

There are also a number of online calculators you can use. See https://duckduckgo.com/?q=suvat+calculator&ia=web

ok so i need to find the mass like in kg? like for an exemple a 5 gallon bucket full of snow

Yes. More important, you need to define "throw" numerically. How high? How fast? Is it fast enough that we need to consider air drag on the thrown object?

well just trying to figure out how much force i need to the pulley to throw snow with a snowblower. thats why i found 500kg of density of snow in the snowblower cylinder that is 14 inch diameter and 5 inch deep roughly. but i might be wrong.

maybe this can't be solve.

also found that 1 cubic foot of water weight 62.4 lbs and they said snow weight around 30% of that.

so trying to calculate how many pounds of water in a cylinder that is 14 inch diameter by 5 inch.

that could give me a rough number in kg than found out how many force that pulley will need to throw that weight.

That puts in context. It is far easier to work with power than speed, acceleration and those equations of motion.

First, figure out how much power your snow blower needs? Then, power=torque*RPM is the remaining formula.

You can buy snowblowers in the store with power ratings from 2 hp to 15 hp or more. Which of those fits your need?

i have everyting settup already but it doenst throw snow so i have to change the pulley and thats why i want to make sure i have the right pulley for the troque

you'll understand better with the video

there's a shaft with 2 3inch pulley that trasmit the torque but they are to small
