This document outlines the steps of a science experiment to determine where to place the fulcrum on a lever to require the least amount of force to lift a 50g load. The experiment found that placing the fulcrum closest to the load at 8cm required only 0.1N/10g of force, while placing it farther away at 15cm and 21cm required more force. This supports the hypothesis that the fulcrum placed nearest the load would require the least force. The student was surprised at how little force was needed and learned levers make work easier by reducing the amount of energy or force required.

Abstract
A process for determining a physical law was executed using the simple pendulum as a
model. The three variables thought most likely to be major influences on pendulum
period were selected. Each variable was tested while holding the others constant.
Displacement affected period, but for displacements less than 10 degrees string length
had the most significant effect on period. The law relating period to string length was
determined. The experimental law did not agree with the accepted law within
experimental uncertainty.

INTRODUCTION AND THEORY
The simple pendulum system was selected to test a method for determining physical
laws. The method was applied to determine which variables influence the period of the
pendulum. The goal was to derive the law that relates the period of the pendulum to the
most significant variables. A diagram of the simple pendulum is shown in Figure 1.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

• http://en.wikipedia.org/w/index.php?title=Lever&oldid=198005759
• Stop Faking It! Energy, by William C. Robertson
Step 3: Question
Where should the fulcrum be placed to require the least amount of force
to lift a 50 g load?
Step 3: Variables
Manipulated Variable: Placement of fulcrum
Responding Variable: N of force or number of grams to move load
Controlled Variables:
• Same cup on each end
• Same Wooden Ruler and pen (as the fulcrum)
• Same amount of load (50 g)
• Newtons or grams measured when ruler is touching the table
• Same amount of tape holding the cup to the ruler
Step 4: Hypothesis WITH Research
I think the fulcrum placed the closest to the ruler will take less newtons
of force or grams, to lift a 50 g load. I think this because I’ve found,
through research, that a fulcrum is part of a lever in a simple machine.
A lever makes work easier and uses less energy or requires less force to
lift a load. I have also noticed that people use levers to help them
complete daily tasks.
2. Step 5: Materials List
Wooden Ruler 12 inches (30 cm)
1 or 2 Plastic Bathroom Cups 3oz (88.7 mL)
Ink Pen with cap
50 g weight
Push Pull Spring Scale or Metal Washers for gram weights
Masking Tape
Step 6: What’s the Plan?
1. Research
2. Details of testing – see variables
3. Measurable results newtons and/or grams
4. Log
5. Repeat test – 3 trials
Step 7: Procedure
1. Build Lever
a. Use 5 cm of masking tape rolled under each cup.
b. If using metal washer to measure grams, place each cup at
the end of the ruler.
c. If using the push pull spring scale to measure, only use one
cup.
d. Put a 50g piece in one cup at the 0 cm end, this is the load.
2. Place the fulcrum, pen, at the 21 cm mark on the lever. Hold pen
in place with one hand.
3. Measuring Force:
a. Use the push end of the push pull spring scale to push down
on the rulers end until the ruler touches the table.
b. Place gram pieces into the cup until the ruler touches the
table.
4. Record results, and repeat two more times for three trials.
5. Repeat procedure with fulcrum, pen, at 15 cm and 8 cm marks on
the ruler.
3. Step 8: Data
Fulcrum Trial 1 Trial 2 Trial 3
21 cm 1.5N / 150g 1.5N / 150g 1.5N / 150g
15 cm .5N / 50g .5N / 50g .5N / 50g
8 cm .1N /10g .1N / 10g .1N / 10g
Step 9: Discussion of Results/Charts & Graphs/Pictures
Setting the fulcrum at 8 cm, which was closest to the load, took the
least amount of effort or grams to lift the load. The lever produced a
force of .1N/10g to lift the load of 50 g. When the fulcrum was set at 15
cm, it took .5N/50g of force to lift the 50 g load. The measurement
furthest from the load produced the most amount of effort with
1.5N/150g of force to lift a 50 g load.
8. Step 10: Conclusion
My hypothesis was that the fulcrum placed closest to the load on the beam
will take the least amount of newtons or grams, to lift the load. The
results indicate my hypothesis should be accepted. The fulcrum placed closest to
the load, 8 cm, took the least amount of effort to move a 50 g load.
This experiment proved that the easiest way to move a load with a lever is to place
the fulcrum close to the load. When the fulcrum was places at 8 cm, it only took a
force of .1N/10g. As the fulcrum moves further from the load, more force is
required to lift the load. At 15 cm it took .5N/50g to lift the load, and at 21 cm it
took even more effort by using the 1.l5N/150g of force.
Even though I was correct in my hypothesis, I was surprised how little force it took
to lift a load of 50 g. I learned that when the fulcrum is placed in the middle, the
work done on the system is equal to the work done by the system. That is why it
took .5N/50g of force to move a 50g load. Through further research I also learned
that each time you change the position of the fulcrum you change the load’s
gravitational potential energy by raising the load up. This means that the effort
arm distance is also changing. So, when moving the fulcrum closer and farther
away from the middle there is a difference in the distance you have to push down
on the effort arm end, which means the load arm requires different amounts of
effort. When the fulcrum is close to the load, the effort arm has a greater distance
to move and the load arm has less of a distance to move. Where the fulcrum is
farther away from the load, the effort arm has a smaller distance and the load arm
has to move the load a further distance. See chart below.
Fulcrum Load Arm Effort Arm
8 cm 1 cm 3.3 cm
15 cm 1.9 cm 1.9 cm
21 cm 2.6 cm 1.2 cm
I have learned that people use fulcrums everywhere is their daily lives to make
work easier. Just in preparing my science project I used scissors and a stapler
which are both levers. Both simple machines make work easier by using less
energy to do work.
Because of the results of this experiment, I wonder if changing the thickness of the
fulcrum would have made a difference in the results. This would be a very
interesting variable to change and see if there is a difference in the results.
