Page 3: Inclined Planes and Pulleys
This page combines the concepts of pulleys with inclined planes, introducing more complex problem-solving scenarios.
Definition: Basit makineler lise kaçıncı sınıf? (Which high school grade covers simple machines?) This topic is typically covered in 11th grade physics (11. sınıf fizik makaralar).
The page presents several advanced problems:
- A pulley system with masses of 10kg and 2kg, calculating acceleration.
- A pulley system on inclined planes at angles of 60° and 40°.
- A pulley system with a 100N weight and a 45° incline.
Example: In the first problem, the acceleration is calculated as 1.67m/s².
Highlight: The page emphasizes the importance of breaking forces into their x and y components when dealing with inclined planes.
These problems require students to apply trigonometry in addition to their knowledge of pulleys and Newton's laws. The concept of tension acting at different angles is introduced, adding complexity to the force analysis.
Vocabulary: LGS makara sorusu (pulley questions in the High School Entrance Exam) often involve similar concepts to those presented on this page.
The problems on this page prepare students for more advanced physics exams, such as the AYT fizik basit makineler (Advanced Placement Test physics simple machines) section.
