go under our bed and etc but when it really occurs we become so terrified and nervous that nothing comes to our mind at that time and before you know it you have been squashed and you are dead ; but those who are Lucky and think quick and take precautions they live. Thus we should be prepared for that time. When earthquakes take place it can cause fires by damaging electrical power or gas lines and become very difficult to stop the spread of a fire as most of the cities roads will be blocked

MECHANICS LAB EXPERIMENT 1 BEAM DEFLECTIONS TEST PERFORMED: FEBRUARY 4‚ 2015 REPORT SUBMITTED: FEBRUARY 11‚ 2015 BY HAGOP MERTEKHANIAN Student I.D # 105200288 Wednesday 7:00 pm GROUP 1 ABSTRACT Deflections of a beam are important to be able predict the amount of deflection for a given loading situation. This experiment addresses determining the yield point for a material to fail‚ so the stress in the material does not have to reach to that point. This is where understanding beam deflection becomes a

Deflection of beams and cantilevers is an important study for clear understanding of behavioral properties of various structural components in aircrafts and around us. Various aircraft structural components such as wing and fuselage ribs and spars (or longerons) require structural analysis for research and cross-examination. Our aim is to study the phenomenal deflection changes experienced during beam and cantilever deflection‚ we will be conducting controlled experiments of various beam materials

Some common types of Bridges include Beam‚ Arch‚ Suspension‚ Cantilever‚ Truss‚ and Cable-Stayed bridges. Bridges are ancient. They have been with us for over 2500 years. The Zhaozhou Bridge is the oldest standing Arch Bridge. It was built in 605 AD. Beam bridges are one of the most simplest types of bridges. The Beam Bridge could be anything as simple as a plank of wood. Or a complex structure. The Beam Bridge is composed up two or more supports that hold up a beam. Arch Bridges are one of the oldest

Solid Mechanics Lab Report Measurement of Young’s Modulus Sherin Joseph 00549618 Measurement of Young’s Modulus of Aluminium using Cantilever loading Abstract The Young’s modulus of Aluminium was calculated using the measurements of the cantilever deflections. A beam of aluminium was clamped on one end and the other end was loaded with different weights‚ ranging from 1 to 15N. The deflection was then measured using a dial gauge. The slope of a load (abscissa) vs. deflection (ordinate)

uncertainties associated with the experimental data. These uncertainties arise due to a random or systematic error. The uncertainties associated with a simple cantilever beam experiment‚ in which the deflection of the beam due to the applied load is recorded with both a dial gauge and a potentiometer. With the most suitable measurements of beam deflection the average value of young’s modulus and the uncertainties associated with that is calculated. The results were in accordance with the theoretical
