Module One Post Five (Bridge types and forces)

Posted on by

This youtube video explains clearly the different types of bridges and forces. There are two forces, tension and compression. Different types of materials are best for withstanding each forces. There are a variety of different types of bridges, and each one corresponds to the forces differently. Depending on the shape of the bridge, certain materials are the best. It also displayed a diagram for where tension and compression are on a truss bridge. From this video I learned the physics in bridge building. I think this will be a good foundation for building my own bridge.

(My own presentation I made on prezi)

Salvador Dalí was born on May 11, 1904, in Figueres, Spain.He would eventually go on to study at an academy in Madrid. In the 1920s he went to Paris and began interacting with artists such as Picasso, Magritte, and Miro, which led to Dalí’s first Surrealist phase. His best known paintinig was created in 1931 it was called The Persistence of Memory (the one with the melting clocks). Dalí died in Figueres in 1989. Salvador Dali use dmany mathematical devices in his art (most surrealist artists used these math devices) like the Golden ratio,measurement, and ratios.

they’re many mathematical devices in art like ratios, ratios are used in poportions of objects or even mixing paints to get a specific colour ratiosare used a lot in art.

 

Module One Post Four(Calculating average velocity or speed)

                                    Calculating average velocity or speed

This video on khan academy show how to calculate two dimensional velocity or speed. It is basically calculating the average speed over a time period. For velocity, you just have to add the direction the object is moving. It might help me in calculating velocity for my project because I’d like to further explore physics – the study of matter in and its motion and behavior through time and space.

                                   Energy transformation on a roller coaster

This website shows the physics in of work and energy in roller coasters. It is helpful because it helps me understand how a roller coaster works. Roller coasters don’t have any engine in them, and they usually only depend on the first propeller in the track. There is usually a motor or a lifting chain at the the beginning of the track. When the roller coaster gains height, it gains potential energy, which is the amount of energy stored in an object due to position. For example, a heavy ball at the top of hill has potential energy because if it falls, their will be a lot of energy in the fall. When the roller coaster falls down the hill, it will lose potential energy and gain kinetic energy, which is the energy of motion. When the roller coaster goes up a hill, it will lose kinetic energy and gain potential energy. Mathematical equation can be used to calculate how much kinetic energy there are. This process is shown on the diagram below.

PART 2

Famous artist M.C. Escher was born June 17, 1898 in Leeuwarden, Netherlands. M.C. Escher created an art style that played with orientation and space. Later embraced  by both artistic and math/sciene communities.M.C. Escher died march 27th 1972.

M.C. Escher’s art often was perspective art and he used lots of math related techniques like the golden ratio, and using diagonal lines to create a perspective.

personally M.C. Escher is one of my top 3 favourite 20th century artists the other two being Salvador Dali and Keith Haring

this website tells me how big of a different in mileage a super big motor to a small motor is. this will helping me compare the amount of gas a 4 stroke motor burns compared to a 2 stroke.this have also included many thing in how the motors are so different and how the different ‘s of the motors might effect on how much gas each of the motors can burn. I think this will help me in many ways and will come in handy when we start to construct our project.

this website tells me how long it take for a full tank of gas to run of. this will help me by letting me compare between a electric engine and a gas. this website actually taught me it all depends on the motor because if you have a small electric motor and a big gas motor obviously the big one will stop working first.overall i think this website will be extremely important to my project in the long run.

this website gives me information about how much a electric motor burns electricity and how quick it runs out of juice/electricity. this will help me by helping me calculate how fast a electric engine will run out so i can compare with a gas. this website have taught me a lot about the differences between how much a gas powered motor and an electric motor.this website was very helpful to read and it just got me one step closer to knowing what Im doing.

this website tells me the difference between a gas engine and a electric motor.this will help me in my project by telling me how much electricity it uses in a regular ride and how much a gas motor burns on a regular ride. In this website a regular ride is two km by the last paragraph of the website it says the gas motor would obviously last longer because electricity burns faster than gas but at the same time your polluting with a gas motor so whose really lasting longer. I think this will be and great help in my project and be a great website to look further on.

this website tells me what the different in aerodynamics of a dirt bike to a car it also tells me the different of gas mileage between a 2 stroke motor and a 4 stroke motor. this will help me by telling me how aerodynamics relate to math.Well it says the 2 stroke dirt bike and a four stroke dirt bike does not really rely on aerodynamics it relies on the power of the motor because two stroke dirt bikes are basically meant to rev really high and four stroke dirt bikes are meant to rev really low and two strokes are also racing motors meant to go on high speeds which four strokes are not, so if there the same cc the 2 stroke will always win.
