B Suggestions for Internal Assessment Project on Young's Modulus

AI Thread Summary
The discussion focuses on conducting an Internal Assessment (IA) in IB physics centered on Young's modulus using stretchy candy snakes as the material. Key considerations include determining whether the stretchy snakes exhibit linear elasticity and the feasibility of designing an experiment to test this. Participants suggest outlining the necessary components of the experiment, such as measuring force and extension. The inquiry emphasizes the importance of understanding the material properties and the experimental approach. Overall, the project aims to explore the relationship between stress and strain in a practical context.

Hi. I am in the IB and am looking at doing a physics IA (internal assessment) on Young's modulus on an elastic material. I was thinking of doing it on the the stretchy snakes like the candy. What would I need to cover in this?
 
Physics news on Phys.org
Is a stretchy snake linearly elastic?
 
Maybe it's a great idea to figure this out by doing an experiment? That shouldn't be too difficult.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
