Whether you buy a used car from a dealer or an individual: Test drive the car under varied road conditions â on hills, highways, and in stop-and-go traffic. Ask for the car's maintenance record from the owner, dealer, or repair shop.
Other top-loading washing machines can spin as fast as 1600 rpm, although these models are usually more expensive. While spin speeds fluctuate by manufacturer and model, most top-loading washing machines have spin rates of about 800 rpm rather than 1600 rpm, which are rarer.
It is linearly proportional to the mass of the object, but the force increases with the square of the rotation speed. Thus, going from 1000 rpm to 10,000 rpm increases the forces involved by a factor of 100. Some practical considerations. So let's say I want to spin two 30 mls tubes of water at 50,000 rpm.
