Design Example: Maintaining Level of an Embankment01:19

Design Example: Maintaining Level of an Embankment

446
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Adjusting a Traverse01:12

Adjusting a Traverse

388
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

Space Trusses01:25

Space Trusses

1.3K
A space truss is a three-dimensional counterpart of a planar truss. These structures consist of members connected at their ends, often utilizing ball-and-socket joints to create a stable and versatile framework. The space truss is widely used in various construction projects due to its adaptability and capacity to withstand complex loads.
At the core of a space truss lies the fundamental unit known as the tetrahedron. This structure is composed of six members that form a three-dimensional shape...

State Space Representation01:27

State Space Representation

596
The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
Consider an RLC circuit, a...

Group Design02:01

Group Design

10.7K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Area of Science:

  • Biomaterials Engineering
  • Orthodontics
  • Structural Analysis

Background:

  • Early loss of molar teeth can lead to significant space loss, impacting occlusion and requiring orthodontic intervention.
  • Existing space maintainers may have limitations in adjustability and precise space management.
  • Preventive orthodontic applications are crucial for guiding proper dental development.

Purpose of the Study:

  • To present a novel, adjustable Cise space maintainer designed for preventive orthodontic applications.
  • To evaluate the structural integrity and performance of the new space maintainer design.

Main Methods:

  • A new space maintainer design was developed using stainless steel, comprising six primary components.
  • Finite element method (FEM) was employed for structural analysis to determine major displacement and stress fields.
  • Analysis focused on stress distribution, displacement patterns, and strain energy density (SED) under load.

Main Results:

  • Structural analysis indicated a linear distribution of critical stresses (σ and τ) along the y-axis, with consistently increasing values.
  • Major displacement patterns were also observed to follow a linear distribution.
  • Strain energy density (SED) was identified as a key factor in determining the critical biting load capacity of the device.

Conclusions:

  • The finite element analysis demonstrates that the adjustable Cise space maintainer is structurally stable.
  • The device is suitable for effectively maintaining and/or regaining space compromised by the early loss of a molar tooth.
  • This design offers a promising solution for preventive orthodontic management of space loss.
