How Long Should the Inclined Plane Be for a 100 kg Box?
Click For Summary
Homework Help Overview
The discussion revolves around determining the length of an inclined plane required to raise a 100 kg box to a height of 5 m using a force of 250 N. Participants explore the relationship between force, weight, height, and the length of the incline, while grappling with the absence of a specified angle of inclination.
Discussion Character
- Exploratory, Assumption checking, Conceptual clarification
Approaches and Questions Raised
- Participants discuss the need to incorporate trigonometric functions such as sinθ or cosθ due to the lack of an angle. There are attempts to derive relationships between the forces acting on the box and the incline's geometry. Some participants express confusion about how to proceed without a defined angle, while others suggest drawing diagrams to visualize the forces involved.
Discussion Status
The conversation is ongoing, with participants providing guidance on drawing free body diagrams and considering the forces acting on the box. There is exploration of various interpretations regarding the incline's angle and its implications on the calculations. Some participants have shared equations and attempted calculations, while others are still seeking clarity on certain aspects.
Contextual Notes
Participants note that the problem does not provide an angle for the incline, which complicates the calculations. There is mention of constraints regarding the maximum angle that can be used without losing the ability to accelerate the mass up the incline.
