Determine bending moment and share force diagram of beam
This document summarizes the bending moment (BMD) and shear force (SFD) calculations for three beam problems. The first problem involves calculating the SFD and BMD for a beam with various point loads. The second problem does the same for a beam with distributed loads. The third problem again calculates SFD and BMD, determining values at specific points along the beam. All problems show the free body diagrams, mathematical equations used, and tabulated results.
Fracture Project Report (2)
This project report analyzes stress concentrations and stress intensity factors (SIFs) for cracks in different locations of a rectangular filleted bar under tension. Cracks were modeled at the shoulder fillet, circular hole, and elliptical hole. Both finite element analysis in ABAQUS and analytical calculations were used to determine nominal stresses and SIFs at each crack location. The results show that the elliptical hole has the highest stresses and SIF, indicating it is the critical region where failure is most likely to initiate. Mesh refinement studies showed convergence of the finite element SIF values with the analytical solutions. Crack extensions were also estimated from displacements near the crack tips.

lab report structure deflection of cantilever
1. This experiment examines the deflection of cantilever beams made of aluminum, brass, and steel when subjected to increasing point loads.
2. The experiment measured the actual deflection of each beam for loads from 0-500g and calculated the theoretical deflection based on the beam's material properties.
3. The results showed aluminum had the largest deflection, brass was intermediate, and steel had the smallest deflection, as expected based on their moduli of elasticity. The actual deflection was always greater than the theoretical deflection.
Chapter 2 basic structure concepts
The cable produces a total pull of 220 kN at the top of the anchorage. Let's break this problem down step-by-step:
1) Resolve the 220 kN force into horizontal (RAH) and vertical (RAV) components:
RAH = 220 cos 30° = 191 kN
RAV = 220 sin 30° = -196 kN (note the negative sign indicates downward direction)
2) The horizontal and vertical equilibrium equations are satisfied:
ΣH = RAH - 0 = 0
ΣV = RAV - (-196) = 0
Therefore, the support reactions are:
RAH = 191 kN
RAV = -196 kN
LAB REPORT SHEAR FORCE IN A BEAM
This experiment examines how shear forces vary with increasing point loads applied to a beam. Theoretical calculations of shear force are compared to experimental measurements. As the applied load increases, both the theoretical and experimental shear forces increase linearly. The experimental shear forces are slightly lower than theoretical values. This shows that the equation used to calculate shear force theoretically accurately predicts the beam's behavior under different loading conditions. The results demonstrate the importance of understanding shear forces in structural engineering design.

It reports the results of the first-order and second-order nonlinear analyses, including displacement and base shear values, ductility and overstrength ratios, and initial and tangent structural stiffness values.Experiment 6 MOS LAB
The document describes an experiment to determine the Young's modulus of elasticity of mild steel, brass, and aluminum using a beam deflection method. The experiment involves applying various loads to beams made of each material and measuring the deflection with a dial gauge. Load-deflection graphs are plotted for each material, and the slope of the graphs is used to calculate the Young's modulus. The experiment found values of 1551 N/mm^2 for mild steel, 3675 N/mm^2 for brass, and 4963 N/mm^2 for aluminum. Precautions taken included carefully handling the dial gauge and ensuring accurate load placement and gauge positioning.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2

1) Resolve the 220 kN force into horizontal (RAH) and vertical (RAV) components:
RAH = 220 cos 30° = 191 kN
RAV = 220 sin 30° = -196 kN (note the negative sign indicates downward direction)
2) The horizontal and vertical equilibrium equations are satisfied:

Therefore, the support reactions are:

RAV = -196 kN
LAB REPORT SHEAR FORCE IN A BEAM
This experiment examines how shear forces vary with increasing point loads applied to a beam. Theoretical calculations of shear force are compared to experimental measurements. As the applied load increases, both the theoretical and experimental shear forces increase linearly. The experimental shear forces are slightly lower than theoretical values. This shows that the equation used to calculate shear force theoretically accurately predicts the beam's behavior under different loading conditions. The results demonstrate the importance of understanding shear forces in structural engineering design.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
