INFORMATION ABOUT THE PRACTICALS ASSIGNMENTS.

Practical work is an essential part of work to be studied in Strength of Materials II. There would be expected of the student to hand in a report after each practical. In this document the student must have its preparation, results and conclusions. The document must be in the format and the same standard of work that you will give to your employer. This report must be handed in one week after completion of the practical for evaluation. The total mark for all your reports and practical tests is 35% of the course mark. An average of 50% for the practical mark must be obtain for admission to the main evaluation
NB: You can be refuse entrance to the laboratory if: o o You did not prepare. You did not have your white coat and laboratory notes.

SAFETY AND SAFETY PRECAUTIONS Introduction

Close attention should be given to all aspects of safety throughout training, and the highest possible standards insisted upon. There is a special need to emphasize the fundamental safety rules of

    Our place of work should have clear written policies and procedures of health and safety. As practitioners we should oversee all health and safety checks regularly. Indoor and outdoor equipment should be checked before and after use. The environment we are using shoul also be checked. Eg, is the glass or gardening tools lying around the garden, are their bricks or toys on the floor on which some one could trip.…

    With this goal of safety on our minds, I believe the bottom line of the emphasis on safety could be considered to be the training that each of us receives in our first weeks on the job as well as the training provided on a regular basis throughout each year of our employment with M-Global, so that we are always aware of how to operate in a safe manner. The training vehicle gives the company the mechanism to provide each of you with the means to become aware of the elements of safety that relate to the specific needs and requirements of your own particular job. Therefore, at this time I have come to the conclusion in the process of the new corporate emphasis on safety to our particular branch that we need to give much greater scrutiny and analysis to the way we can prevent accidents and emphasize the concern of safety at every stage of our operation for every employee. Toward this end, I have asked the training coordinator, Kendra Jones, to assemble a written training program that will involve all employees which will be implemented beginning no later than June of this year. When the plan has been written and approved at the various levels within the office, I will conduct a meeting with every department in order to discuss all details of the safety program.…

    The training should allow you to have a knowledge of the fundamental health and safety procedures for your workplace so that you can practice and promote safe working procedures. You should set and maintain high standards of care for yourself and others and you should also adopt and promote a culture of safe practice. It is important to use constructive criticism to improve your professional practice and you must work as a team to make sure that the practices are correct for the workplace you are in. The Cherry Trees Children’s Centre did not have the safety that was needed because they knew that there were cracks in the metal tubes that formed the structure of the frame and this should have been fixed before the children were allowed to play on the structure. They would have to make sure that they make sure that there are no sharp objects around on the floor where the children are playing because they could trip, fall and injure themselves. The girl that fell from the climbing frame was not checked properly as they were told that they had just grazed their leg but in fact they had broken it. The health and safety at this time was not correct because the adults who were there were volunteers who had not been told about the safety regulations…

    An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force of gravity of other objects.) • The object is moving with constant velocity. In this case, the object may be subject to a number of forces which cancel out or no force at all. This case is not considered in this lab. The category of physics problems that involve forces in static equilibrium is called statics. Physicists and engineers are subjected to static problems quite frequently. A few examples of these principles in use are seen in the design of bridges and the terminal velocity of a person falling through the air. Mathematically, forces in equilibrium are just a special case of Newton’s Second Law of Motion, which states that the sum of all forces is equal to the mass of the object multiplied by the acceleration of the object. The special case of forces in equilibrium (static), occurs when the acceleration of the object is zero. When this situation arises, Newton’s Law becomes: ΣF = 0 (1.1)…

    Occupational Safety Rules

    • 10 Pages

    Being knowledgeable enough about the safety rules is the real essence of Occupational Safety and Health. I chose this topic (safety rules), not because our group conducted a report about this during prelim. That’s just a simple reason. Definitely, I picked this one because I was able to visualize the usefulness of safety rules when the time comes that I need to face the real world. That real world pertains to a suitable job for me in the near future, wherein I am responsible to apply what I had gained during college years. Safety rule is really applicable since my course is Bachelor of Science in Business Administration major in Operations Management. After all, in any type of occupation, it is a necessity that there must be a safety precautions or rules to follow.…
