Transcribed Image Text:**Text Transcription for Educational Website:**
"The crate is pulled via a uniform, massless cable that is attached to the crate at an angle, θ."
**Diagram Explanation:**
The image consists of a mechanical diagram depicting a block (crate) on a surface. The following elements are shown in the diagram:
1. **Block (Crate):** The block is represented as a rectangle labeled with "m," indicating its mass.
2. **Surface:** The block rests on a horizontal line representing the surface.
3. **Cable:** A diagonal line extends from the top of the block at an angle, denoted as θ (theta) from the horizontal.
4. **Tension (T):** An arrow originates from where the cable contacts the block, extending in the same direction as the cable. This arrow represents the tension force, labeled as "T."
The diagram illustrates the setup for analyzing the forces acting on the block due to the tension in the cable, with the angle θ being a critical component in the problem.
