Lever Balance Displacement Calculation

Click For Summary
The discussion focuses on designing a force balance lever system where an initial mass m maintains equilibrium on a capacitor plate. As the voltage increases, the force of attraction, Fatt, between the plates changes, affecting the displacement of a second mass M. The user seeks an equation to determine how the height of mass M varies with the increasing force of attraction. The conversation emphasizes the need for a calculation method for displacement in this context. Understanding the principles of balance and force dynamics is crucial for accurate displacement calculations.

Hello I am trying to design a force balance lever system. Basically the initial state will in a force balance equilibrium. That is, there will be a mass m placed onto of the capacitor plate to keep the lever balanced. I will then ramp the voltage of the capacitor up, causing a force of attraction, Fatt, creating by the plates attracting one another.

I want to know an equation for finding the distance displacement for the other mass M? How much will its height from the floor vary with increasing force of attraction, Fatt?

I thank you all in advance

N.B I have already figured out how to calculate the Faa, so there is no need to worry about that.

Basically all this is,is a old fashioned weighing scales balance and I want to know how you calculate the displacement
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
