🪙 Coin Pusher Lab: Granular Friction, Pile Pressure and Expected Payout

Discrete-element model of tokens on a shelf with an oscillating pusher plate: Coulomb friction, stick-slip, force chains, conservation of coins and a replicated experiment that measures the expected payout with confidence intervals.

⚙ Under the hood

A 2-D discrete-element model of tokens on a shelf with an oscillating pusher plate, Coulomb friction, stick-slip, force chains and side gutters. Experiments check the pusher force against mu*N*m*g and measure the expected payout and gutter share with 95% confidence intervals over replicate runs.
