How do you design a bridge with these materials?

AI Thread Summary
To design a bridge using drinking straws, dressmaker's pins, coins, bond paper, and sticky tape, it's essential to consider key engineering principles. The bridge must support its own weight and the weight of the coins while addressing structural challenges like span length and torque. Utilizing triangular shapes can enhance stability and resistance to bending. Additionally, the orientation of materials plays a critical role in the bridge's strength. A clear understanding of these concepts will aid in successfully completing the project.

how do you build & design a bridge with these materials?

4 drinking straws
10 pieces dressmaker's oin
5 pieces of 5-peso coins (the bridge should be able to withstand the weight of these coins)
1 short bond paper
and a
1 meter sticky tape


Anyone who has performed this project already? Please! I'm in dire need of help.

and by the way, i need a thesis regarding this! please! help me! :smile:

This appears to be schoolwork. Tell us your ideas and let us know where you are stuck.

To help you get started, remember that engineers are problem solvers. So first you determine the problems to be solved such as: the length of the bridge's span; weight to be supported, including the bridge's own weight; dealing with torgue on the structure (in large suspension bridges this is partly handled by the width of the structure and by placing a curve toward the end on one bank); type of foundation and location of foundation points. These are some of the possible problems to be considered.

Tell us your ideas so far.

Agreed. Moved.

Think "Triangles."

Also, an object with a longer dimension perpendicular to the direction of bending resists bending better than a "flatter" object.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
