Geometry Discrete Problem Thanks

In summary, we are given a problem where an advertising sign is supported by a horizontal steel brace and a wire attached to the building at an angle of 25 degrees. The force of gravity acting on the sign is 850N and we need to find the tension in the wire and the compression in the steel brace. To solve this problem, we need to draw a free body diagram of the end of the brace where the forces are acting. Then, we can use trigonometry to find the tension and compression forces by setting up a right angle triangle with the forces as the sides. It is important to note that the compression force is actually directed outwards, not inwards as commonly thought. By following these steps, we can solve for

An Advertising sign is supported by a horizontal steel brace extending at right angles from the side of a building, and by a wire attached to the building above the brace at an angel of 25. If the force of gravity on the sign is 850N, find the Tension in the wire and the compression in the steel brace

You should post your attempts at the problem as well, not just the question. But to get you started, draw a free body diagram around the end of the brace, where the steel, wire and advertising sign all meet, and resolve the forces.

You have the EXACT same textbook as me!

This question is actually really easy once you understand a couple key things. You must first draw a diagram, and remember your arrows on your vectors. Also, it is a common misconception that for these types of problems the compression force is inwards (so in this case toward the building). Actually, the force is outwards. Once you realize this you can simply set up your vectors forming a right angle triangle...use trig to solve.

Post the steps you have, I'm not going to give you the answer, so I'll check your work with mine (my math teacher confirmed mine is correct). Good luck.
 

FAQ: Geometry Discrete Problem Thanks

What is a discrete problem in geometry?

A discrete problem in geometry refers to a problem that can be solved using discrete mathematics, which involves finite, distinct values or objects. This type of problem often involves counting, number theory, graphs, and algorithms.

How is geometry used to solve discrete problems?

Geometry can be used to solve discrete problems by providing a visual representation of the problem and its solution. It can also be used to create geometric models that can be solved using mathematical principles.

Can you give an example of a discrete problem in geometry?

One example of a discrete problem in geometry is the "Seven Bridges of Königsberg" problem, which involves finding a path that crosses each of the seven bridges in the city exactly once. This problem can be solved using graph theory and Euler's formula.

How are discrete problems in geometry relevant in real life?

Discrete problems in geometry have many real-life applications, such as in computer science, engineering, and physics. They can be used to optimize routes for delivery trucks, design computer algorithms, and model complex systems.

What are some strategies for solving discrete problems in geometry?

Some strategies for solving discrete problems in geometry include breaking the problem into smaller, more manageable parts, drawing diagrams or models to visualize the problem, and using mathematical principles and formulas to find a solution. It can also be helpful to work through similar problems and practice applying different techniques.
