Moment of inertia

Then, we measured the radios and the mass of the platter. In addition, we use the equation for inertia I=(1/2)MR^2. Depending on the result from the previous steps it has to be determined if equations A=(mgr/I) and T=mg are the easier equations to solve the problem. Then we had to predict on graphs (A vs m), (A vs r), (A vs I). (A) being Angular acceleration, (I) inertia, (r) radius, and (m) mass, prediction (Pic1). When setting the platter make sure to use the bubble level in order…

2 Loads and Structural Stress Because of the energy content of the wind is relative to the cube of the wind speed, turbine blades exposed to wind speeds will be under an enormous amount of stress. In order to diminish the impact of wind speeds, turbine manufacturers develop the rotors on them with few blades somehow they are as narrow and long as practical (Pinting ZHANG and Shuhong HUANG 2011). The maximum efficiency from such blades can be attained based on the pitch at an optimum angle…

‘Push it to the edge’ (or on the edge (of the skateboard)) -Cesar Castro I used to hate people who rode those silly planks on wheels. However, as an attempt to learn something new and foreign I decided to meticulously study the dynamics between science and skateboarding (soon to be my second favorite thing). While doing my preliminary research (finding a skate shop, buying equipment, and finding skate spots) I learned that almost every aspect of skateboarding is scrutinized to the point where…

distance from the axis of rotation (through the middle of the gymnast's body). They can then extend their body to slow down when landing or twisting. You can also see this in the equation Iω=Ifωf (I is inertia, and ω is angular velocity). When in the tucked position, the gymnast creates a lower moment of inertia, which in turn creates a greater angular velocity. Greater angular momentum means they have the potential to do more flips. The gymnast gains angular momentum by pushing off the surface…

• Wheel Diameter is taken as 26 inch (0.6604 meter) so radius of the wheel is taken as 0.33 meter.(5) • Drag co efficient is taken as 0.9 from book High-Tech Cycling by Ed Burke.(6) • Wheel Inertia is calculated by assuming the mass of the E-Bike tire which is 1.2 Kg and radius is 0.33 meter so the inertia of the wheel becomes 0.13068 and for two wheels it is taken as 0.2613 Kg.m^2. • Motor torque, Brake torque, Gear Torque values are taken my team mates who are designing Motor, Brake, Gear.…

looks like the wilderness, he is having anxiety as he realizes that what he is doing, that is cheating on his wife, is no better, or is even worse than what he caught his daughter doing, which is why he does not get that mad at her. It is in this moment he has a sense of guilt, and has a time to reflect on his actions, but it is still not when he becomes conscious of the absurd. Likewise, when Mikey tragically dies in the ice storm, the person to stumble upon his lifeless body on the ground is…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

ambitious to become more informed, but he realizes that he will never be informed enough, and this is a constant struggle for him. He also comes to the realization that after 40 years, he still has no use for anything he learned at Harvard. At this moment, Adams is giving an effort to become informed but is helpless because he has no efforts from a teacher. Adam’s struggle, like the struggle between the science and religion, can also be found in“Vis Inertiae”. This chapter is not as much focused…

The reason for choosing this piece of work was because out of all the books I had gone through pertaining to the Northern Renaissance period, this one jumped out at me the most. The incredible attention to detail and the intrigue of possible symbolic meaning behind it drew me towards wanting to learn more about it. Andrea Mantegna became well known for his attention to detail and linear sharpness of his art during the Northern Renaissance period, and he stands out for his devotion to classical…

The similarities and differences of Kinetics of a Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a…
