## Activity 2 Simple Machines Practice Problems Answer Key

Illustrations should consist of basic simple machine functional sketches rather than realistic pictorials. Surface area is the sum of all the areas of all the faces or surfaces that enclose a three-dimensional solid. Older people remain in the population, many generations can be represented. Use this information to answer the following questions. This example is only one engineering application of physics and the mathematics associated with the properties of solids. Explain any additional information and necessary formulas.

If you were to fill a glass with water and place it in a tub full of water, the glass would sink. The volume of water that your body displaces has weight. The resistance, when balanced, is measured at 42 lbf. Назва Activity 2 Simple Machines Practice Problems Answer Key Дата канвертавання 06. Both strands are used to change direction.

The board is made from southern yellow pine, which has an air dry weight density of. The screw is an inclined plane and is being slid up the entire way. All problem calculations should assume ideal conditions and no friction loss. What factors contributed to the world's overall population growth in the last 150 years. The width, depth, and height dimensions of the board are 3. How is it that these vessels do not sink straight to the bottom of the sea floor? The answer again deals with weight, average density, and volume. The word average is used, because skin, bone, hair, and muscle tissue all have different weight densities.

## (KEY) Graphing the Human Population

Make sure that your graph is a full page in size and you have the correct labels for the X and Y access and a title for your graph. The majority of the volume of a ship is air. Round your answer to the nearest quart. Values should range from 1650 to 2020. This is the reason why ships are able to float. The concept of area typically refers to the amount of space that is contained within a two-dimensional shape. In this case, the majority of the volume of the space that is taken up by the glass is the air on the inside of the glass, which is significantly less dense than water.

## Science Questions and Answers

The weight density of metal is higher than the weight density of water; therefore, the volume of water that is displaced by the coin cannot weigh as much as the coin itself. Place time on the horizontal access. The effort force is larger when the effort is applied to the axle. If you were to place the same glass in a tub full of water, but with no liquid in the glass, it will float. The length from the wheel and axle to the effort is 5 ft. How does surface area differ from area? Like metal, glass has a weight density that is greater than water.

Engineers design vessels to travel on and under the surface of the water. If your average weight density, or the average amount of weight per unit volume of your body, is less than the weight density of the water, then you will float. Explain the role of each strand. The weight density of cast iron is. Therefore, the average weight density of the glass is less than the weight density of water.

Area is the measure of a two-dimensional surface. In the 19th Century, the agricultural revolution increased food production. The load is distributed over the two strands, one is combined to ceiling and the other is under the weight. . If you were to drop a coin in the water, you would notice that it sinks. If the weight of the displaced water pushing upward is greater than your weight, then you will rise out of the water to a point where equilibrium has been achieved. Values should range from 0 to 20 billion.

Industrialization, health care, sanitation 2. The height from the ground to the top of the stairs is 2 ft. The threads are slanted and the wedge pushed through the material. Volume is the measure of a three-dimensional space. Why does a population not level off during the same year it reaches zero population growth? You will then apply your knowledge by calculating these properties for each of your puzzle piece solutions.

The valve will encounter 200 lb of resistance force applied to a 1. The reason has to do with the concept of buoyancy. The length from the wheel axle to the center of the load is 2 ft. The shear has a ¼ inch thick cutting blade with a 45 degree slope. It took 1649 years for the world population to double, going from.
