Thermodynamics: Discussion Questions

Prevents loss of time and delays in order to clear up mess before using equipment.

With the worm screw being in constant contact with the worm wheel, there has to be consideration of wear due to friction when selecting the material. In order to avoid amounts of wear that will be detrimental to performance, the shaft’s material must have a high surface hardness1. It’s important that this is achieved without the hardening of the entire thread because this will result in the material becoming more brittle. A

“Force is defined as an object that has the capacity to cause change in motion” (McLester & St.Pierre, 2008,. 93).

* Healing: When the epidermis breaks away due to a minor cut or burn, the cells on the lower layers of the skin migrate upwards as a sheet. When two ends of the sheet meet, the cells stop growing due to a process called 'contact inhibition'. Thus, the epidermis is sealed and the skin returns to normal.

In conclusion the relationship between the properties of skin and friction skin impressions is that without these characteristics or capabilities fingerprints wouldn’t exist. The

That’s one of them. Good job. What body part do we use in order touch things?

Pain and temperature change often precede skin color changes. This injury results from intense and/or prolonged pressure and shear forces at the bone-muscle interface. The wound may evolve rapidly to reveal the actual extent of tissue injury, or may resolve without tissue loss (Wolters Kluwer Health, 2017).

Pressure Ulcer is a breakdown of skin appears on the skin over a very thin or bony prominence

5. What’s really meant is that the forces are the same but going in different directions as a mirror image of one another. So when one force is going for example 2 newtons in a positive direction, the same amount is going in the opposite direction.

These blisters usually just appear on uncovered skin, such as the face and hands, but can also be found anywhere on the body once they have taken root.

This is the variable I will get my data from.the way the amount of friction affects the speed of the toy car because the amount of friction slows the speeds of moving objects this happens because the force of friction causes a opposes the motion of an object causing it to lose speed. The less speed the toy car has the longer the car will take to travel the distance of the two binders. Water is a lubricant a lubricant is something that lessens friction therefore it should make the toy car insell in speed making it go

     Drag force is the cost of increasing downforce. Drag force is the force acting on an object in motion in the opposite direction the object is moving through a fluid (Yager). To most people drag force is simply known as air resistance. The objective of aerodynamic efficiency is to maximize downforce while minimizing drag force.

When two objects get in contact with each other the force between them forms. Scientists call this force the frictional resistance, or friction. It occurs because of the imperfections in the surfaces of objects, the molecules of both surfaces interfere with each other creating a natural force between two objects. The friction opposes direction of motion of the object and is parallel to the surface on which the action takes place. The force and magnitude that are necessary to overcome friction can be calculated. Area of objects that is involved in the contact is disregarded when calculating friction.
