Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

### Thermodynamic Processes of Air

Air undergoes two processes in series:

#### Process 1-2:
- **Type:** Polytropic compression
- **Polytropic index (n):** 1.2
- **Initial pressure (P1):** 140 kPa
- **Initial volume (V1):** 0.8 m³
- **Final volume (V2):** 0.04 m³

#### Process 2-3:
- **Type:** Constant pressure process
- **Final volume (V3):** V₁ (= 0.8 m³)

### Task:
- Sketch the process on a Pressure-Volume (P-V) diagram.
- Determine the work done from Process 1 to Process 3.

### Detailed Guide:

1. **P-V Diagram Sketch:**
- **Process 1-2** will be a curve showing the polytropic compression from (P1, V1) = (140 kPa, 0.8 m³) to (P2, V2) on the P-V diagram. Since it's a compression, the curve should slope downwards.
- **Process 2-3** will be a horizontal line moving from V2 back to V1, indicating a constant pressure process.

2. **Determine the Work Done:**
- **For Process 1-2 (Polytropic Process):**
\[
W_{1-2} = \frac{P_1 V_1 - P_2 V_2}{1 - n}
\]
- **For Process 2-3 (Constant Pressure):**
\[
W_{2-3} = P_3 (V_3 - V_2)
\]
- **Total Work (W):**
\[
W_{total} = W_{1-2} + W_{2-3}
\]

Make sure to substitute the known values into the formulas to calculate the specific work done in each process.

A string is stretched so that it is under tension and is tied at both ends so that the endpoints don't move. A mechanical oscillator then vibrates the string so that a standing wave is created. The dark line in each diagram represents a snapshot of a string at an instant in time when the amplitude of the standing wave is a maximum. The lighter lines represent the string at other times during a complete cycle. All of the strings are identical except for their lengths, and all strings have the same tension. The number of nodes and antinodes in each standing wave is different. the lengths of the strings (L) and the amplitudes at the antinodes (A) are given in each figure.
