Question

Transcribed Image Text:**Problem Description:**
A puck weighing 9 lb rests in equilibrium on the frictionless surface of a ramp, held there by ropes AC and BC. The task is to determine:
- The normal force the ramp exerts on the puck.
- The tension in each of the two ropes.
**Diagram Explanation:**
The diagram shows a ramp inclined in relation to the x, y, and z coordinate axes. A puck (C) is positioned at the center of the ramp, with ropes extending from points A and B to C. The layout includes:
- **Rope AC:** Extends from point A to point C on the ramp.
- **Rope BC:** Extends from point B to point C.
The triangle involving points A, B, and C forms the spatial setup of the ropes and ramp.
**Variables and Dimensions:**
The dimensions relevant to the problem are listed below. The variables correspond to different length dimensions in the setup. Note that the diagram may not be drawn to scale:
- \(a = 44.0 \, \text{in}\)
- \(b = 48.4 \, \text{in}\)
- \(c = 24.2 \, \text{in}\)
- \(d = 50.8 \, \text{in}\)
- \(e = 50.6 \, \text{in}\)
- \(f = 12.1 \, \text{in}\)
- \(g = 71.3 \, \text{in}\)
**Objective:**
By analyzing these dimensions and the equilibrium conditions, calculations can be performed to find the required forces and tensions.
