The electrons are accelerated to a speed close to the light along with an evacuated tube and in order to generate an X-ray beam‚ the electrons are being deflected as a general rule to 90o via electromagnets to hit the target. The electrons quickly reduce their speed‚ giving up their energies to high-energy X-radiation because the electron energies involved are so greater compared

CHAPTER-1 GENERAL OVERVIEW 1.1 INTRODUCTION: In an automobile headlight‚ a ’meeting’ beam (dip beam) is provided in addition to the driving beam (high beam) so as to reduce the dazzle for those approaching head-on to the vehicle. The Auto Dipping Device for a head light is intended to automatically change the Headlight Circuit to either driving beam or dip beam given a particular set of road conditions‚ without the intervention of the driver. The present practice is to operate the dip

Looking at the data from testing other bridges‚ the bridges who double bonded their wood at the bottom last a lot longer that the one piece of wood. My bridge failed when one of the connecter beams became unattached to the beam. Also with the structure you have to be very careful how you glue your beams together and making sure they are cut perfectly. The structure will be messed up if the measurements are not exact and precise. To make the structure stronger you have to make sure each sides of

CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted‚ reflected off a target and then returned as an echo. Radar makes use of a phenomenon

weight before breaking. The four main types of bridges are: beam‚ arch‚ suspension and cantilever. The most commonly used bridge is the beam bridge. The beam bridge is made up of a horizontal structure and two or more vertical structures on either end for the horizontal structure to rest on. Beam bridges can be as simple as a fallen log across a river. In society‚ engineers generally make beam bridges out of steel and concrete. Because beam bridges‚ or any bridge for that matter‚ are required to

uniform beam 6.0 m long‚ and with a mass of 75 kg‚ is hinged at A. The supporting cable keeps the beam horizontal. If the maximum tension the cable can withstand is 2.4 ×103 N‚ what is the maximum mass of the load? 20 kg 4. A 75 kg painter stands on a uniform 5.0 m board of mass 16 kg supported horizontally by two ladders. Find the forces exerted by each ladder on the board. FR = 593N‚ FL = 299N 5.

INTRODUCTION Basic structural learning begins with an analyzing of a simply supported beam. A beam is a structural member (horizontal) that is design to support the applied load (vertical). It resists the applied loading by a combination of internal transverse shear force and bending moment. An accurate analysis required in order to make sure the beam is construct without any excessive loads which affect its strength. A bending moment exists in a structural element when a moment is applied to

reinforced concrete beam shown in Figure 1 carries an imposed live load of 12kN/m2 and a dead load of 12 kN/m2 as shown in the diagram. Given‚ fcu = 30 N/mm2‚ fy = 460 N/mm2‚ fy‚ links = 250 N/mm2. The beam is exposed to a mild condition. a) Determine whether the beam is singly or doubly reinforced beam. b) Determine the main reinforcement for the beam using a design chart. c) Determine the shear reinforcement for the beam. d) Check whether the deflection of the beam is acceptable.
