Fracture mechanics

Fig. 5 shows the monotonic and cyclic stress-strain responses of selected specimens having all influential parameters considered in this study, such as the volumetric ratio of transverse steel reinforcement, number of CFRP layers, and aspect ratio. In this figure, the axial stress was calculated by dividing the axial load to the column cross-sectional area, and the corresponding axial strain was derived from the average readings of the four LVDTs divided by the central gauge length of each…

Explain how Newton 's first law applies to air bags, seat belts, and headrests. Newton’s first law applies to air bags, seat belts, and headrests in terms of keeping your body at rest while you are driving, which in turn will keep you safe. When you crash your car, the motion of your body in the car matches the motion of the century itself, so when it crashes, your body has the tendency to stay in motion. So, with the headrest, seatbelt, and airbag, they are all designed to slow down the forward…

In 1964 a physicist by the name of Peter Higgs took some ideas that were floating around at the time, added an insight or two of his own, and proposed that there was an energy field that permeated the entire universe. This energy field is now called the Higgs filed. The reason he proposed this field was that nobody understood why some subatomic particles had a great deal of mass, while others had little and some had none at all. The energy filed that Higgs proposed would interact with the…

Three tests are done through a Gizmo to determine how radius, mass, and velocity affects centripetal acceleration of an object undergoing uniform motion. The results show centripetal acceleration is affected by radius and velocity but not mass. It gives a better understanding to why objects in uniform motion accelerate towards the centre of a circle. Introduction The purpose of this lab is to determine how the radius, mass and speed of an object can affect the centripetal acceleration of the…

A world leading physicist, astronomer, natural philosopher, alchemist, theologian and mathematician, Sir Isaac Newton is known globally for being one of the most influential men to ever live. Newton was born on Christmas day, 1642 in Woolsthrope-by-Colsterworth, United Kingdom where his grandparents raised him. In the beginning Isaac was heavily pressured into being a farmer, however he was so terrible at farming they decided to send him to university. At 19 Isaac attended his first classes at…

This paper will discuss the life of the German mathematician, astronomer, and astrologer Johannes Kepler. Who had a great impact in the 17th century scientific revolution, because of his development of the three laws of planetary motion. He is also remembered for the legacy he left that later provided one of the foundations for Isaac Newton's theory of universal gravitation. “Johannes Kepler was born on December 27, 1571 poor and sickly in what is now Germany. His father left home when Johannes…

It is often said that there is no such thing as a bad day on the golf course, but if you find yourself playing 18 holes when the wind is howling you might be rethinking that sentiment. If you are familiar with the nuances of big island golf, you know that in Hawaii the wind will definitely blow. There are few things more frustrating for a golfer than to see a ball fly straight off the club— and then watch the wind take it far, far off course. Waikoloa Village Golf Club in Waikoloa, HI, would…

1 The Nature All my life through, the new sights of Nature made me rejoice like a child. – Marie Curie (1867-1934), the Polish-French physicist chemist famous for her pioneering research on radioactivity. She was the first person honored with two Nobel Prizes in physics and chemistry. All that is beautiful, delightful and affable in this world, the silence of the night, the loveliness of the morning, the beauty of the day, the melody of the breeze, the fragrances of the flower, the precious…

PE Coursework Strengths The sport I have chosen is football. One of my main strengths (components of fitness) in football is my speed. The definition of speed is the ability to move quickly across the ground or moving limbs rapidly to grab or throw. In football, you use your speed for e.g; When you’re attacking and you are dribbling past a defender, you can use bursts of speed to blow past him. This means I get closer to the goal and have a better chance of scoring for me and my team. Also,…

TASK 4(P4):- Discuss the effect of loading structural material 1) You need to discuss the effect of compressive force, tensile force, shear force, bending force on structural member 1) Timber: Compressive force on timber: - The effect of a compressive force on a timber is a change in structure of a material and to carry a load within its limits. Tensile force on timber: - The tensile force is the pulling force exerted on both the ends of a timber. Both the ends of a timber will undergo tension…
