The primary disadvantage of friction is that it can cause wear and tear on surfaces, leading to increased maintenance costs. In addition, it can cause objects to move more slowly than they would without friction, reducing efficiency. Finally, friction is often a source of unwanted noise and heat.
Area increase pressure decrease . Find situation where the principle is applied ? 1. Weather patterns: As atmospheric pressure decreases due to an increase in area, wind speeds increase. 2. Oceanography: As surface area increases, pressure from the atmosphere decreases, resulting in lower ocean depths. 3. Automotive engineering: As the area of the piston in …
Atmospheric pressure can be measured using a barometer. A barometer is an instrument that measures the pressure of the atmosphere by measuring the height of a column of liquid, typically mercury, in a glass tube.
which are the situation where atmosphere pressure is used? Aircraft and spacecraft propulsion Heat pumps and air conditioning systems Vacuum systems Automotive engines Refrigeration systems Fuel cell systems Chemical and pharmaceutical process engineering Thermal power plants Steam turbines Gas turbines Aerospace engineering Robotics 13. Motors and generators Solar energy systems Instrumentation systems
Atmospheric pressure is the pressure exerted by the atmosphere of Earth (or that of another planet) on the surface of that planet. It is generally measured in millibars (mbar) or hectopascals (hPa).
Liquid pressure is the pressure exerted by a liquid on the walls of its container due to the force of gravity. The pressure is caused by the weight of the liquid. The pressure increases with depth as the weight of the liquid above the point of measurement increases.
Weight is a measure of the gravitational force of attraction between objects, and is usually expressed in units of mass (e.g. kilograms or pounds). Weight is related to mass, but the two are not the same. Mass is an intrinsic property of an object, while weight depends on the strength of the gravitational force between …
Thrust is a force that propels an object forward. It is generated by the reaction of a system that pushes an object in a specific direction. Pressure is the force applied perpendicular to the surface of an object per unit area. It is calculated as the force divided by the area. Thrust is a force …
Use lubricants: Lubricants reduce friction by forming a thin layer between two surfaces, reducing the direct contact between them. Increase the surface area: Increasing the surface area of the two surfaces in contact reduces the friction because it allows the force to be spread more evenly over the surface, reducing pressure. Use ball bearings: Ball …

The shape of a car or plane is designed to be aerodynamic and efficient. An aerodynamic shape reduces drag, allowing the vehicle to move more efficiently through the air or water. Additionally, the shape of a car or plane affects the way it handles and performs. The design of the vehicle can help ensure passengers …
