Final Milestone Part 1 Rube Goldberg Machine

Rude Goldberg Machine is based on conservation of energy, i.e. energy is always conserved in a

process; it is described with the following equation:

PE (t=0) +KE (t=0) =PE (t=tf) +KE (t=tf) +W (done by system).

Where PE represents potential energy and is most commonly in the form of gravitational potential

energy (mgh, where m is mass, g is the acceleration of gravity and h is height) or elastic potential

energy (0.5kx^2, where k is the spring constant and x is the displacement of the spring from rest

length).

KE represents kinetic energy (0.5mv^2 were m is mass and v is velocity).

W represents work, which can be cause by an object moving against friction or heat generation or

desired work done.

The purpose of my Rube Goldberg Machine is switching on the reading light in my room in two

steps.

Step 1: A ball of radius r and mass m is placed on the slanted platform and disturbed from its

equilibrium position.

In rolling down without slipping for a distance of S down the inclined plane. During the roll, the

height of rolling ball changes by h units.

In rolling down the inclined plane, the potential energy (mgh) is transformed into linear and

rotational kinetic energy.

Step 2: The rolling ball hits the stick placed vertically immediately at the bottom of the inclined

plane. The vertical stick is nailed in the middle so that it can oscillate left and right about its middle

point. As the rolling ball hits the wooden stick, the momentum of the rolling ball is transferred to

stick.

The lower portion of the stick will move left while the upper portion of the stick will move right,

effectively tapping the electric switch of the reading light. In this process, the velocity of the rolling

balls reduces to zero and, as the Newton’s second law, change of momentum is equal to Ft .

mv = Ft

The force is applied to the stick which brings the stick into action and makes a movement towards

left direction.
