Metals are more ductile than predicted by the model where all atomic bonds move simultaneously during deformation, which would require too much energy. Dislocation theory, where deformation occurs by the motion of individual atoms or lines of atoms called dislocations, requires less energy and better predicts the observed strength of metals.
The wave equation describes the propagation of waves through space and time. It can be written as the second derivative of the displacement with respect to time equals the speed of the wave squared times the second derivative of the displacement with respect to position. The document discusses rewriting the wave equation in different forms and solving problems using it to analyze exam questions.
This document proposes concepts for a future city called Sugarbangers City. It discusses ideas for security including using mechanized robots for patrols and combat suits for human police officers. Tourism would be promoted through maintaining cleanliness, building attractions like theme parks near beaches. Green building practices would minimize environmental impact through strategies like using renewable energy and natural daylight. Transport options include hover bikes and flying bullet trains. Disaster relief infrastructure would consist of underground refugee shelters and rescue robots. The city would implement energy management practices like using low-energy housing and solar power. It would also have advanced water and waste management systems and increased hospitality education and jobs.
The lumberjack was out chopping wood when he heard a roar in the distance and saw flames shooting out of the trees. An ice dragon had awakened after thousands of years and was destroying the lumberjack's village. The lumberjack rushed to the village and threw his axe at the dragon, hitting it in the chest. The dragon dropped dead, saving the village from further destruction. The villagers were grateful to the lumberjack for defeating the dragon that had been terrorizing their land.
The three factors that resistance depends on are length, cross-sectional area, and resistivity. Resistance is directly proportional to length and resistivity, and inversely proportional to cross-sectional area. Resistance can be calculated using the resistivity equation: R=ρL/A, where ρ is resistivity, L is length, and A is cross-sectional area. As temperature increases, resistance increases in metals but decreases in semiconductors due to increased scattering and freed electrons respectively. Measurement errors should be considered, such as calculating percentage errors in cross-sectional area and resistance.
Young's Modulus is a measure of the stiffness of an elastic material and can be represented graphically. A typical Young's Modulus graph plots the stress along the x-axis against the strain along the y-axis, showing a linear relationship between stress and strain for an elastic material within its elastic limit. The slope of the linear portion of the graph gives the value of Young's Modulus, which is a material property that does not depend on the size or shape of the material being tested.
This document defines key terms related to Young's modulus including:
- Stress is the force applied per cross-sectional area of a material.
- Strain is the extension in length resulting from stress.
- Brittle materials break without plastic deformation.
- Elastic materials return to their original shape after deformation.
It also provides examples of materials that exhibit properties such as being stiff, elastic, plastic, ductile, malleable, strong, brittle, tough, smooth, and durable. The document outlines measurements needed to calculate stress and strain and discusses working out uncertainty when multiplying or dividing units.

Hooke's Law states that the extension of a spring is directly proportional to the force applied. It can be written as Force = Spring Constant x Extension. Young's Modulus is a material property that indicates how much a material will deform under stress. When stress is applied to a metal, the positive ions will spread apart as the atomic bonds stretch like springs. If the metal is within its elastic limit, it will return to its original shape when the stress is removed.
The document provides development proposals for an unused plot of land in Kuala Lumpur, Malaysia from two students.

The document describes a site surveying fieldwork involving a closed loop traverse using a theodolite. Key steps included setting up the instrument and marking stations A, B, C and D. Field angles were measured between stations and used to calculate distances, azimuths, latitudes and departures. The total angular error was distributed and corrections applied to adjusted values. Station coordinates were then computed, with the traverse closing within the acceptable accuracy range for land surveying of 1:300. The purpose was to gain practical experience in traversing techniques.

It includes the objectives, introduction to leveling concepts, equipment used including an auto-level and tripod, field data collected using rise and fall and height of collimation methods, adjusted data tables, and a two peg test summary. The leveling resulted in a small misclosure error of 0.011m, within the acceptable accuracy limit, and corrections were made by distributing the error evenly across readings.

Their objectives were to educate students about stress, invite them to participate in a stress talk, conduct a survey on sources of student stress, and provide stress-relieving games. The team prepared for the event, set up their booth, conducted the survey, and concluded that they successfully spread awareness about managing stress.
The document summarizes a student group's final presentation report on their campaign to raise awareness about stress and ways to reduce it. The group organized an event with booths, games, and a survey to educate other students on stress. They designed posters and activities like throwing written stresses into a bucket. Most group members reflected that they learned about stress management and developed new skills in planning, communication, and teamwork through this project.

Accounting final project - financial ration analysisSheng Zhe
LBS Bina Group Bhd is a property development and investment holding company in Malaysia. It operates through five major segments: property development, management and investment, trading and others, construction, and racing circuit. The document analyzes LBS Bina Group's financial ratios from 2012-2013 which show improving profitability, adequate liquidity but high debt levels. It also examines the company's share price performance relative to the KLCI stock index from January to December 2015, finding mixed results of outperforming and underperforming the market at different times.
1) The group was assigned a project to create a video implementing concepts from social psychology. They developed a storyline where two students decide to go shopping but change their minds and join two other students to study together.
2) They filmed scenes showing social influence, first impressions, extrinsic motivation, observational learning, and building self-efficacy. One student is initially studying alone but joins others influenced by their invitation. Others notice a hard-working student and decide to emulate her studying.
3) On exam day, all four students feel confident in their ability and beliefs that studying as a group helped prepare them. They hoped to achieve better exam results through collaborating and supporting each other's self-efficacy.
