Employee Voice According to Brinsfield (2015) for production to take place all the factors of production needs to be organized by their owners in a way that is profitable and effective. This factors of production are capital, entrepreneurship, land and labor. All the factors of production are important but labor is very unique in that labor cannot be treated like the other factors of production. Labor is derived from human beings who have needs, objectives and feelings and thus they cannot be regarded

1. Does the force or torque in drilling change as the hole depth increases? Explain. How then, would you then change the feeds and speeds as the hole depth increases? Generally, as the hole depth increases, the force or torque in drilling also increases because as the depth increases, the surface contact area will also increase which increases the required force to drill the hole. Therefore, it increases the required torque. As the hole depth increase, the feed and speed reduce because the drill

Verification of Newton's 2nd Law of Motion Introduction The objective of this lab was to test Newton's 2nd law of motion, which states that the acceleration of an object is proportional to the sum of forces acting on it and inversely proportional to its mass. This was done by connecting a cart to a hook with a string and using a smart pulley to measure the acceleration of varying masses on the hook as it falls down. System mass remains constant. A free body diagram and applying Newton's 2nd Law

Home Health Care and Pressure Sores The best way to deal with pressure sores is to prevent them from ever happening in the first place. Once they occur, pressure sores are quite difficult to treat and can cause a number of very serious complications. Home health care aides can help your senior loved one take the steps and precautions necessary to avoid getting pressure sores. Pressure sores are also known as bedsores, pressure ulcers, and decubitus ulcers. Regardless of what you call them, they

Abex® Expands Its RSD-Certified Brake Lining Range Just recently, Federal-Mogul Motorparts has expanded its Abex® Reduced Stopping Distance (RSD) certified commercial grade friction lining range to include a brand new lining that surpasses both the OE brake manufacturer standard for 23,000-pound tractor applications and the Federal Motor Vehicle Safety Standards (FMVSS) 121 Reduced Stopping Distance (RSD) requirement. In a test performed by an ISO-certified facility, utilizing a tractor equipped

The car is pulled to the top of the first hill using chains and an assortment of gears to pull the car to the summit of the roller coaster. Then it turns the potential energy into kinetic energy as the car excels down the hill at high speeds. After this the kinetic and potential energy rock back and forth throughout the thrilling ride. At the beginning of a roller coaster a winch pulls the car to the top of the ride. This energy does not disappear but is instead saved up by the car the higher it

The ring sling baby carrier works through a delicate balance of tension and friction that is needed to lock the metal rings into place. The baby’s initial weight placed in the sling, adds tension to the fabric that translates up to the metal rings and causes enough friction to lock the rings; therefore, the sling is locked in place. There are many variations of the ring sling baby carriers. Ring slings were developed using

Who: 24 year old, David Smith from Northern British Columbia. David had worked for White Pass and Yukon Route for four years. Others whom were involved in this incident were the conductor, the locomotive engineer, and the other heavy equipment operator. All there were seriously injured though they all survived the crash. There were no witnesses besides all the individuals who were on the scene, the people involved in the crash. The person carrying out the investigation is an agent from the Transportation

move, in a rotational motion. Especially in dance. The cartilage, also referred to as the labarum, is a rubber seal to protect the head of the femur and the acetabulum from causing friction against each other. When the labarum becomes worn or weak the head of the femur and the acetabulum will come into contact, friction will be caused creating excruitiating pain in the hip, which is also what causes Hip Osteoarthritis. Especially in dance, Hip Osteoarthritis does commonly occur for people in their

To what extent is roller coaster designed by physical principles? --By Wayne Wang Introduction: The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. It gives people a strong sense of excitement and attracts millions of tourists throughout the world. In most people 's first impression, roller coaster looks not safe at all and it seems that the trains could run out of tracks and crash on the ground at any time. In fact, the average death rate of roller
