Scotty’s father‚ explained what happened and then went to the hospital in the ambulance. When the father arrived the mother informed him of the condition of their son. The doctors ran many test and came to the conclusion the he suffered a hair line fracture of the skull‚ a mild concussion‚ and the deep sleep was due to the shock caused by the impact of the car. The doctor assured both parents that everything would be fine and not to worry. Howard was concerned but not nearly as much as Ann. Ann

EFFECTS ON FATIGUE CRACK GROWTH AND FAILURE IN A RAIL STEEL 1. Increasing R (ratio of minimum to maximum stress) was found to both accelerate cracking and reduce the critical crack size at instability (alternating or pulsating loads? Or nearing fracture?) 2. The equation of Forman et al. relating crack growth rate to ∆K and R gave the best fit. It is used to predict life in the finite range of S-N curve. 3. Pulsating load = zero-to-tension loading 4. Fatigue crack growth rate = dldN

that Nadine had an open‚ tibial-fibular fracture just below the knee. Fig 1. Open tibial-fibular fracture9 Tibia and fibula are the two bones located right below the knee area; out of the two the tibia is the weight bearing bone‚ which means that tibial fractures are usually linked with fibular fracture‚ due to the impact tibia would have on fibula 1. In open fracture‚ the broken bone tends to penetrate the skin‚ while in a closed fracture it doesn’t 2. Due to breaking of the

Aircraft structures Abstract: The aircraft structure is an important part where the structure of an aircraft depends on the optimum requirement of the customer and the environments in which it will be going to fly for the major time. It has to go several checks at regular interval of flying hours under proper inspection. This paper contains the basic information regarding the components of an aircraft and the basic concept of its design. The main criteria of design and its philosophy is the

affected by osteoporosis but men with testosterone deficiencies are at risk as well. Women that are low on estrogen in their bodies are at higher risk. Heredity particularly on the maternal side is a risk factor; and if a person has had a bone fracture in their life is also at risk. Some of the most preventable risk factors for osteoporosis are alcohol abuse and cigarette smoking. Lack of calcium and vitamin D in your diet over your lifetime is another huge risk factor.

over its lifetime produced higher than estimated bending forces on the system and induced fluctuating stresses on the braking rod that it could not sustain. Crack propagation developed in the rod due to bending stresses and eventually extended until fracture occurred‚ sending the cage of men to the bottom of the shaft at nearly 30 miles per hour. This paper examines the loading situation and presents a solution in regards to materials engineering‚ which would have prevented accident. Based on the loading

The Ankle Brachial Pressure Index is a test that demonstrates the cardiovascular status of the lower limb. It is a quick‚ noninvasive way to check for risk of peripheral artery disease (PAD). Peripheral artery disease is a condition in which the arteries in the legs or arms are narrowed or blocked. People with peripheral artery disease are at an increased risk of heart attack‚ stroke‚ poor circulation and leg pain. If the foot pulses can be clearly felt then the risk of vascular disease and associated
