Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane‚ and on the same block sliding down an inclined plane. This was done by first testing block‚ and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms‚ and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

1. Sangha is the monastic order that developed from the Buddha’s early disciples- accepted people from all castes and levels of society. It provides a calm environment‚ freedom from external pressures and responsibility. The Buddha founded in Sangha in order to provide such objective conditions. 2. Samsara is a clean escape from the karma-run wheel of birth‚ death and rebirth (samsara). The importance of Samsara is it’s what makes everything work. If there was no cycle of life and death than you

Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction is experimentally

This paper is to identify possible sources of intergenerational friction‚ and to describe how this differences could be managed in occupational setting. Today is the time when multiple generations are working side by side. Each generation has some distinctly different expectations and perceptions about what their working environment will provide and how they should behave as employees. Therefore‚ many organizations today are challenged by intergenerational issues they have never experience before

As habitat fragmentation in southern California split land‚ the integrity of the land changes. Habitat fragments that each has a decrease in area will have an increase in the total perimeter distance collectively (Morrison et al.‚ 2006). This increased area around the habitat exposes more of the internal habitat to the elements‚ reduces the habitat buffer‚ and in turn creates less optimal habitat for species in the fragment (Morrison et al.‚ 2006). This process‚ called edge effect‚ decreases the

EFFECT OF SURFACE AREA ON AIR FRICTION Design Background Information: Air resistance‚ also called drag‚ is the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Size and shape are the two factors that affect air resistance. Air resistance depends on the surface area‚ so‚ as the surface area increases‚ the air resistance increases. When an object is falling‚ air resistance acts to push it back up. This is
