Friction and Dynamics of Rock Avalanches Travelling on Glaciers

- ... This indicated that the friction coefficient of a rock avalanche on a glacier was not constant. Before constructing the model, preconditions were established from simple experiments that determined the basic attributes of solid objects travelling on ice. The preconditions were that heavier weight caused more energy to dissipate and a larger layer of lubrication (therefore less friction). Rock sliding on ice behaves in a similar way to a rough metal sliding against a soft metal. In both cases, one digs grooves in the other, (and the rate of erosion is dependent on the angle at which the grooves are dug.) Through collecting data quoted in other studies with regard to friction’s role in r...   [tags: history, collection of data]

The strong frictional force that acted against the ball, caused the ball to have the slowest time. For example, water had the smallest frictional force which was 8.73 × 10-4 N, but syrup had a frictional force of 2.9x10-3 N and the time it took the ball to fall through the water was .16 s and for syrup was 5.03 s, which took longer than water .Therefore, the ideal frictional property that the U.S....   [tags: Science, Friction ]

Manufacturing Principles Case Study Report Bearings

- Introduction There is a market need for a device that allows constrained relative motion between two or more parts in a rotational or linear sense without causing excessive wear. The bearing is intended to fulfill this need by providing a smooth surface and mechanism that allows a shaft or component to move independently without causing damage in the form of wear to its support. Bearings themselves can be classified in terms of the motions that they allow, the particular principle of operation that they implement and the direction of applied loads that they are capable of handling....   [tags: Physics ]

At an angle of 45 degrees, the Brakeman position results in the lowest drag. The shape of the nose, although the fore body pressure drag is not very large and does not change much at low speeds for different shapes, it has great influence on the flow over the rest of the sled. It has influence on the transition from laminar to turbulent flow. Two modifications are tested on a quarter scale model and finally, flared sidewalls, by gradually accelerating the flow over the sidewall, it should flow along the wall further without being diverted and sucked into the cavity....   [tags: Force, Classical mechanics]

Physics of Stopping a Bike

- In short brakes are a tool that turn kinetic energy into heat(http://en.wikipedia.org/wiki/Brakes). This is accomplished by applying friction in one way or another. In the case of disk brakes friction is created because the braking mechanism exerts a force on the break pads which pushes them into contact with disk. It is this contact combined with the fact that the disks are rotating that causes kinetic energy to be converted to heat. If the purpose of brakes is to convert kinetic energy into heat, then in order to know how much heat the brakes make requires that we find out how much kinetic energy there is in a moving bicycle....   [tags: physics bicycle]

- Swimming is simple; it consists of two parts -- pulling and kicking. However, swimming is not all about strength, technique, or skill; it is also about fluid dynamics, drag reduction, and body structure. Due to drag reduction, some swimmers will go to extremes to reduce drag. How efficiently a swimmer kicks and pulls is also influenced by the viscosity of the water (the thickness of the water). As well as having strong muscles throughout the body because almost every muscle is used while swimming, there are many variables that effect the speed of a swimmer....   [tags: water sports techniques]

The Physics of Soccer

- Rolling Motion and Friction Suppose you kick a soccer ball without giving it any spin. Your foot, therefore, gives the ball an initial speed (v) and an initial angular speed of 0. Since grass is not frictionless, the ball initially slides across the field, then starts to rotate and, eventually, starts rolling without slipping. A soccer ball rolls without slipping when its center-of-mass speed equals its angular speed (around its center of mass). OK, now suppose you want to kick the ball so that it immediately starts rolling without slipping....   [tags: physics sport sports soccer football]

It is the natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an oject in motion will maintain this state of motion. This is often called the law of inertia. Consider for instance the unfortunate collision of a car with a wall....   [tags: Newton's First Law Essays]

Ball Bearings

- The 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. Other types of bearings have developed from these basic designs, like double-row and deep groove bearings, to handle specific application....   [tags: essays research papers]
