When does a man exert more pressure on the floor.
Pressure of ballerina exert on the floor. A 520 n ballet dancer is balanced on the toe of her shoe. Nail tips exert tremendous pressures when they are hit by hammers because they exert a large force over a small area. The contact area between the surface and object has a very small effect on the pressure. Pressure only depends on the weight of the object which didn t change.
For example mercury is more dense than water and it is heavier. Use graph paper to measure the area presented by each foot when standing normally. Si units derived units and prefixes will be used throughout. Surface area of one foot is less than two feet.
What force must be exerted on a nail with a circular tip of 1 00 mm diameter to create a pressure of 3 00 10 9 n m 2 this high pressure is possible because the hammer striking the nail is brought to rest in such a short. So when you lie down the force of your weight is spread out over a. You may have been warned about swinging around on one leg of a chair.

Again liquid pressure weight density depth why does the pressure depend on the weight density. A small hydraulic jack exerts a force of 2200 n. Apart from the risk that you will damage the chair or hurt yourself the chair leg can damage the floor. While standing or while walking.
Pressure is the force exerted on an area divided by that area. It is common to use the word depth instead of height when talking about pressure. While walking one foot is in contact with the ground at a time. If the toe has an area of 0 0010 m 2 what pressure does she exert on the floor.
The person would exert only slightly more than 80 000 pa of pressure on the floor.
