MHB Centripetal Force Calculation: How Many G's Can Your Centrifuge Simulate?

AI Thread Summary
The discussion focuses on calculating the centripetal force generated by a centrifuge designed to simulate increased gravity. The formula for centripetal force is derived from the relationship between mass, velocity, and radius. With a centrifuge spinning at 35,000 rpms and samples positioned 1.75 inches from the center, participants are tasked with determining how many times the force of gravity (9.81 m/s²) can be simulated. The conversation emphasizes the importance of understanding the acceleration due to gravity in these calculations. Ultimately, the goal is to quantify the centrifuge's capability to replicate gravitational forces.

#1 Round and round we go! You are constructing a centrifuge to use its spinning motion to act like increased gravity.
(a) Find the formula for centripetal force.
(b) Your centrifuge can spin at 35,000 rpms and your samples are placed 1.75 inches from the center of rotation. If the force of gravity is g = 9.81m/s2, how many times the force of gravity can your centrifuge simulate?

That last bit should read, "If the acceleration due to gravity is..."

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
