High Duro Meter 3 The Boot Wheels
463 wordsThe diameter is the height of the wheel, which ranges from 43 to 80 mm. As diameter increases, cruising speed increases and maneuverability decreases. (2) The duro meter is the hardness of the wheel. Wheels use the A scale from 0 - 100. 100 would be a very hard plastic. Softer wheels have more shock absorption, greater turning ability, and wear faster. (2) A wheels profile is the point where the wheel touches the ground. Traction and stability increase with an increasing profile thickness. (2) T...

Ball Bearings Cm
1,060 wordsSC 1: Investigating Terminal Velocity When an object falls through a fluid it accelerates until it reaches its terminal velocity. At this speed the forces acting on it are balanced. My task is to investigate the factors that affect the terminal velocity of a falling object. I am going to investigate how mass affects the terminal velocity. I think that as the mass of the ball bearing increases so does the weight of the ball bearing, which requires more friction to balance the ball bearing's weigh...

Filling Slot Bearings Single Row Bearing Balls
424 wordsThe object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring, which have raceways, or slots, grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types. Oth...

World War Ii Black And White
1,230 wordsA hurried businessman runs across the airport at a full sprint. If he doesnt get to Gate D 3 in three minutes, he will miss his flight to Singapore. As he is running, little beads of sweat begin to form on his brow. People gawk at him and hurl insults his way when he bumps past them with seemingly no thought. All of a sudden, the man stops in full stride, whining to a stop. He breathes heavily and looks to his right. How can he go on the plane without something to read? Quickly the man bounds ov...

4,557 wordsPhysics CAT One Extended Untitled Physics CAT One Extended Practical Investigation Report Student Number: Purpose The Purpose of this investigation is to explore how the terminal velocity of a sphere falling through glycerol varies with the temperature of the glycerol and the size of the sphere. Introduction In the early stages of the project it was intended to investigate how the speed of a sphere falling through glycerol varies with the size of the sphere. However, after analysis it was decide...

2 Nd Edition Ball Bearings
1,460 wordsOver the years of history, there have been many civilizations. We will look at the earliest of all civilizations known to man. From Village to City began in 8000 BC and spanned all the way into 3000 BC. Throughout this report we will look at the 6 key features of this civilization as outlined in our classroom discussions, and hope to convey what we have learned in a useful, and interesting way. The development of a city: The first city to be built was Jericho, in the Middle East Map: This map is...
