Pedestal Grinder A Pedestal Grinder is primarily used in Design & Technology for heavy general purpose grinding operations. Grinding is the process of removing material by the cutting action of the countless hard and sharp abrasive particles of a revolving grinding wheel as they come in contact with the surface to be ground. The grinding wheels are held between two flanged disks. Usually a roughing or coarse-grained wheel is mounted on one end of the spindle and a fine wheel on the other. A tool rest is provided for each wheel so that the work piece may be held or steadied while being ground. The operator is protected against flying abrasive particles and ground material by the wheel guards and spark arrestors, which are integral parts of a machine. Safety glass shields are also provided for additional protection. WARNING The main types of injury are caused by: • Entanglement of hair or clothing in rotating machinery parts. • Fingers being caught between grinder wheel and work rest. • Sparks or worn abrasive may be thrown by the grinding action. • Body parts coming into contact with abrasive wheel. • Ejected material or disintegrated abrasive wheel. • Hot metal.

Adams spent 21 years at Rhode Island College, serving as an Assistant Athletic Director in addition to his coaching duties. He officially retired in September of 2000 and then went on to work part-time as a supervisor at the college’s Recreation Center until the fall of 2008. He will be inducted into Rhode Island College’s Athletic Hall of Fame this October. The James “Jimmy” Adams Fund has been established in his honor, with all proceeds benefitting RIC student-athletes. Please contact the RIC Athletic Department at (401) 456-8007 to make a contribution to the fund.

Turn the steering wheel from stop to stop several times. Do not hold it against the stop. 8. Again start engine and turn steering wheel from stop to stop several times (avoid turning fully against stops as much as possible). Recheck fluid level and fill as required. If there is evidence of fluid foaming, turn off engine and wait an hour for foam to clear.

Introduction Everybody knows that when you press your foot on the brake pedal the vehicle is supposed to stop. But how does the pressure from your foot get to the wheels with enough force to stop a heavy vehicle? In the following sections, we will study the systems and components required to allow brakes to work effectively. Course Objectives Upon completion of this course, technicians should understand and be able to apply their knowledge of: • • • • • • • • • • • • Brake functions and components Split hydraulic systems Master cylinder operations Balance control systems Power brake booster systems Disc brake operation Micrometer reading Drum brake operation Brake fluids Brake bleeding operations Brake lines and hoses Basic diagnosis Using the Job Sheets As you proceed through the online module, on some pages you will find links that will open a window with a printable procedure or job sheet containing hands-on lab activities based on the NATEF standards related to the content you are studying. When you come upon a procedure or job sheet link, click on it and print the job sheet for completion in the shop. See your instructor for guidance in completing the job sheets. Some jobs sheets will require supplemental materials such as a vehicle service manual, equipment manual, or other references. Brake System Functions Automotive brakes are designed to slow and stop a vehicle by transforming kinetic (motion) energy into heat energy. As the brake linings contact the drums/rotors they create friction which produces the heat energy. The intensity of the heat is proportional to the vehicle speed, the weight of the vehicle, and the quickness of the stop. Faster speeds, heavier vehicles, and quicker stops equal more heat. Automotive brake systems can be broken down into several different sub-systems (fig. 1): • Apply system • Boost system • Hydraulic system • Wheel brakes • Balance control system • Warning system (fig. 1) Base Brake Systems .

Henan Li Marine Technology Submission date: June 2012 Supervisor: Svein Sævik, IMT Norwegian University of Science and Technology Department of Marine Technology THESIS WORK SPRING 2012 for Stud. tech. Henan Li Flexible Pipe Stress and Fatigue Analysis Spennings- og utmatnings-analyse av fleksible stigerø r The flexible riser represents a vital part of many oil and gas production systems. During operation of such risers, several failure incidents may take place e.g. caused by fatigue and corrosion. In limit cases where inspections indicate damage, the decision making with regard to continue operation or replacing the riser may have large economic and environmental consequences. Hence, the decision must be based on accurate models to predict the residual strength of the pipe. In most applications, one or several steel layers are used to carry the hoop stress resulting from internal pressure. This is further combined with two layers of cross-wound armour tendons (typically 40-60 tendons in one layer installed with an angle of 35o with the pipe’s length axis) acting as the steel tensile armour to resist the tension and end cap wall force resulting from pressure. The riser fatigue performance may in many cases be governed by the dynamic stresses in the tensile armour. The existing lifetime models for such structures is primarily based on inherent assumptions with respect to the slip properties of the tensile armour. This thesis work focus on establishing a FEM based model for analysis of the tensile armour, so as to analyse the stress and slip behaviour when exposed to different load conditions. The thesis work is to be based on the project work performed and shall include the following steps: 1) Literature study, including flexible pipe technology, failure modes and design criteria, analytical methods for stress analysis of flexible pipes,...
