contained two tables which show the results collected from the experiment. It has included four diagrams, two tables and discussion section for results. Theory[1] Rigid Rotor: Working speed is lower than the lowest-order critical speed of the rotor is called rigid rotor. Static balance: It is a balancing which included determining primary force into the current plane. Then, added a suitable mass in the position of the plane…

Trains are one of the oldest and essential source of transportation. One big machine produces massive power to pull the mass 8 or 10 times of its mass on steel tracks and transports it to thousands of mile between the cities. Steam engines power the trains in its initial stages. Now, Diesel Engines and Electric power trains are used. There are four forces acts on a train. One of them is its weight which balanced by the typical reaction of the tracks. The third one is the thrust force produced by…

make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down, it is best to push it down as close to vertical as it can go so that the weight can fall the farthest distance, and so that the sling can get pulled with greatest possible horizontal starting force. As soon as the sling is past the trough it is lifted up and away. Then it is swung out in a partial arc because of…

these forces. the only forces exerted upon the riders are the force of gravity and the normal force The force of gravity is at all times directed downwards and the normal force is at all times directed perpendicular to the seat of the car. Since the orientation of the car on the track is continuously changing, the normal force is continuously changing its direction. Feelings of weightlessness and heaviness are associated with the normal force; they have little to do with the force of gravity.…

very complex to model. It has a significant effect on the amount of power required for removing a given volume of metal, surface quality of the finished product, and the extent of tool wear. However, many studies assume no friction in the metal cutting process due to lack of experimental techniques to directly measure the coefficient of friction. Sticking and sliding regions are the two contact regions along the tool-chip interface. A critical friction stress τ_c and coefficient of friction µ…

Isaac Newton’s Laws of Motion and Crumple Zones Crumple Zones design and function The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle…

In the conventional lift a more erect and upright back alignment is required. If done correctly, the conventional style deadlift builds the muscles of the backside, including spinal erectors, hamstrings and glutes. This causes lifters to struggle to get the weights off the floor, but makes lockout easy. One thing to be cautious of when conducting a conventional style deadlift is shear force from hyper extending the lower back. (Ez) According to a study of two male regional powerlifting…

When society breaks down, death and destruction incur. In the book The Lord Of The Flies by William Golding the effects of the breakdown of society is a major theme. Humans identities are formed when society’s rules and laws are non existent, and humans are forced to rely off of their own morals. This can be seen when Ralph’s tribe is demolished by Jack because of Jack 's different ideology . In addition, Piggy’s logic and intelligence when talking about advanced topics on the island also show…

say the least, “Motion is the actuality of what potentially is.” (Kosman, 1969, p. 40) Although Aristotle thought long and hard specifically about planetary motion, he never answered the question of whether celestial bodies moved, and if so, by what force. Abu ‘Ali Ibn Sina, a Muslim scholar in 1000 AD, confirmed Aristotle’s suspicions by saying, “Nobody begins to move or comes to rest of itself.” (Hecht, 2015, p. 80) Almost seven hundred years later Newton will state this fact in his First Law,…
