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.

Question

**Problem Statement:**

A light bar $ AB $ supports a 15-kg block at its midpoint $ C $. Rollers at $ A $ and $ B $ rest against frictionless surfaces, and a horizontal cable $ AD $ is attached at $ A $. Determine:
(a) the tension in cable $ AD $,
(b) the reactions at $ A $ and $ B $.

**Diagram Explanation:**

- **Bar AB**: A horizontal bar supported at point $ A $ and point $ B $.
- **Block at C**: A 15-kg block hangs from the midpoint $ C $ of the bar.
- **Distances**:
- $ AC = 250 \, \text{mm} $
- $ CB = 250 \, \text{mm} $
- **Vertical Measurement**:
- Distance from $ B $ to the wall is $ 350 \, \text{mm} $.
- **Rollers**: Located at points $ A $ and $ B $ against frictionless surfaces, allowing the bar to rest and rotate slightly.
- **Cable AD**: A horizontal cable attached to point $ A $ and extending to point $ D $.

**Objective**:

Determine the tension in the cable $ AD $ and the reaction forces at the supports $ A $ and $ B $.

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.
