In summary, the project requires building a cantilever structure using newsprint, thread, and masking tape that can only weigh 350 grams and support 1 kilogram while stretching 12 inches off a surface. The proposed solution involves using truss-like structures, multiple layers of newsprint, and various folding and weaving techniques to distribute weight and add strength. Reinforcement with glue or resin may also be considered. Experimentation with different designs is crucial to finding the most effective and lightweight solution.

Homework Statement


as a project we need to build a cantilever structure out of newsprint, thread, and masking tape. It can only weigh 350 grams and has to support 1 kilogram, and must stretch 12 inches off of a surface. We have an idea, but we don't know how to make it stronger while keeping it under the 350g weight limit.


Homework Equations





The Attempt at a Solution


im thinking we are going to use truss-like structures and build an arm hanging off the table with 6 total trusses and build it taller than it is wide so there is less sagging of the structure.

We will also use multiple layers of newsprint to add strength and stability. Additionally, we can use different types of folds and weaving techniques to distribute the weight evenly and add strength to the structure. Another option would be to reinforce the structure with a thin layer of glue or resin to add rigidity and prevent sagging. It is important to experiment with different designs and techniques to find the most effective and lightweight solution.

1. How do you calculate the necessary dimensions for a 350g newsprint cantilever?

To calculate the necessary dimensions for a 350g newsprint cantilever, you will need to use the formula F = (3/2)WL, where F is the force or weight being supported, W is the width of the cantilever, and L is the length of the cantilever. Rearrange the formula to solve for W, as this is the variable we are interested in. The resulting value will be the minimum width needed for the cantilever to support 1kg.

2. What is the maximum weight that a 350g newsprint cantilever can support?

The maximum weight that a 350g newsprint cantilever can support will depend on its dimensions and the length of the cantilever. Using the formula F = (3/2)WL, you can calculate the maximum weight that can be supported by your specific cantilever. Keep in mind that the longer the cantilever, the lower the maximum weight it can support, and vice versa.

3. How long should the cantilever be to support 1kg?

The length of the cantilever needed to support 1kg will depend on its width and the weight of the material used. Using the formula F = (3/2)WL, you can rearrange the formula to solve for L, the length of the cantilever. This will give you the minimum length needed to support 1kg with your specific cantilever dimensions.

4. Is newsprint a suitable material for building a cantilever?

Newsprint is a suitable material for building a cantilever as long as it can support the necessary weight and has the proper dimensions. Newsprint is lightweight and can be easily manipulated to create the desired shape and dimensions for a cantilever. However, it may not be as strong or durable as other materials such as metal or wood, so it is important to consider the specific needs and requirements of your project before choosing newsprint as the material for your cantilever.

5. Can the 350g newsprint cantilever be used to support a weight heavier than 1kg?

The 350g newsprint cantilever can potentially support a weight heavier than 1kg, but it may not be stable enough to do so consistently. It is important to carefully calculate and test the dimensions and weight limits of your cantilever before using it to support a heavier weight. Additionally, consider using a stronger or more durable material if you need to support heavier weights on a regular basis.
