Moment of inertia

information about Newton was that the apple story was not true. He later stated that an apple never fell and hit him on the head. While on his family farm he was in their apple orchard and witnessed an apple fall from a tree which sparked an “aha” moment in his head. There was no real evidence or account that an apple actually fell on his…

a force applied on an object it changes its inertia and causes to changes its state of rest or motion. The structures should be in equilibrium before and even after the application of the force. So the two important things in the civil engineering are the force and equilibrium. Thus the force when applied to an object it may changes its equilibrium so there should be some knowledge…

and resistance properties of different plant species were tested. RAHMEYER et al. (1999) stablished a relationship between the force required to bend the plant to an angle of 45 degrees in terms of the plant’s modulus of elasticity (E) and its moment of Inertia. VAN DE WIEL (2003) suggests that this relationship can be generalized to: F_α= 6EI/H^2 (sin⁡α )^2 (10) By definition, the force Fα applied to the vegetation equals the drag force FD applied by the flow. The…

There is a common phrase that goes: “A picture is worth a thousand words” When applied to writing, can we say that short stories are the picture to a novel's’ video? Countless authors have turned to short stories to give the readers a snapshot of a moment in time and presumably, a plot that takes place in limited time. In the cases of Deborah Eisenberg and James Joyce, they employ a unique theme that fits perfectly into the short trajectory of the story. Eisenberg and Joyce exemplify paralysis…

Biomechanics refers to the “study of the action of external and internal forces on the living body, especially on the skeletal system” (Dictionary.com, 2015). By using biomechanics we can examine and find ways to successfully enhance performance, develop exercise programs and modify sporting techniques (Swedan, 2013). This paper will be analyzing and evaluating the athletic event of high jump. Biomechanics will be applied to critically examine the techniques used in high jump and improve upon…

Trampolines are very fun toys, is an activity loved by people of all ages. A trampoline is an object consisting of a piece of taut, a strong fiber extended over a steel frame using many springs, the fabric used on the trampoline bed has certain elasticity, the elasticity is generated by the springs connected to the frame, which store potential energy (the stored energy of position of an object). The first trampoline to be invented, was invented by a trapeze artist called Du Trampolin, he…

When the rotor rotating, due to the centrifugal force caused by each eccentric mass are not on the same plane, thus, the formation of the inertia couple, the rotor is still unbalance. This process of balancing called dynamic unbalance. Mechanical condition of dynamic balance: Both of the sum of the vectors of each eccentric mass 's inertial force and the moments of them are zero. ∑▒F1=0 , ∑▒M1=0 Figure 2.2: The detail drawing of the theory of the dynamic balance. Unbalance mass on…

Five... People are anxious for this moment to be a success. Four... U.S. citizens grit their teeth, hoping the lift off will be a success. Three... Butterflies. Butterflies fill stomachs during this nerve racking moment. Two... Families of Buzz Aldrin, Neil Armstrong, and their crew hold their breath. One... Blast off. Cheers ring all across the country, “to the moon!” Rather to a deserted area that could serves as a good representation to the moon. There is an abundance of evidence supporting…

In the third and last section of Half Brother, the plot should have started heavily picking up, but even at the end of the book, the plot progresses at a snail's pace. There is an argument to be made on how slow plot progression is a characteristic of a well-written book, but when it’s consistent throughout the entire book it just makes for a dull experience. The main progressions are that Zan gets sent away, brought back, and then sent away again. This is just sloppy writing. During the third…

Angular velocity, with the addition of a product’s moment of inertia is what creates an angular momentum quantity (Bi 2014). Moving objects keep a constant velocity, however, if acted on by outside forces this would not occur. Say a moving object like, the planet Saturn keeps this constant speed, it thus keeps a constant momentum, since the system is conserved. This conserved system of the planet Saturn would be referred to as angular momentum, since Saturn rotates about an axis. Saturn is also…
