When a simple machine is used to perform a task what factors may be affected?
the amount of force needed to perform the task the distance over which the force is applied the direction in which the force is applied
What is the term for a tool that makes work easier by changing the size or direction of a force?
The term for a tool that makes work easier by changing the size or direction of a force is "simple machine." Simple machines are fundamental mechanical devices that allow us to multiply or redirect the force applied to accomplish tasks more easily. There are six types of simple machines: **Lever:** A lever consists of a rigid bar (lever arm) that rotates around a fixed point called a fulcrum. Levers can change the amount of force applied or the distance over which the force is applied. **Wheel and Axle:** A wheel and axle consists of a large wheel connected to a smaller axle. When force is applied to the wheel, it can change the direction of the force and multiply it. **Pulley:** A pulley is a wheel with a groove that a rope or cable can run through. Pulleys are used to lift or move objects and can also change the direction of force. **Inclined Plane:** An inclined plane is a flat surface that is angled. It allows objects to be moved up or down with less force over a longer distance. **Wedge:** A wedge is a triangular-shaped object used to split, lift, or secure materials. It transforms a force into two forces acting in different directions. **Screw:** A screw is an inclined plane wrapped around a cylindrical post (called a screw thread). When the screw is turned, it converts rotational motion into linear motion, making it useful for lifting or holding objects. These simple machines form the basis of more complex machinery and tools we use every day. They enable us to perform a wide range of tasks with less effort by altering the magnitude or direction of forces.
What do all simple machines have in common?
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load.
How do you convert MWh to MW?
MWh is a unit of energy whereas, MW is a unit of power. Energy and power are two words often confusingly interchanged. Energy is the amount of work done, whereas power is the rate of doing work. One MWh (Mega Watt Hour) is a million watts of power applied over the period of an hour. One MW (Mega Watt) is a million watts. 1 Watt is 1 Joule per second. To convert MWh to MW, you should divide MWh by the time applied in hours. MWh = MW * Hours, and respectively MW = MWh / Hours E.g. Some electrical equipment used 84 MWh is the total energy measured by a electricity meter over 12 hours operation. What is the power rating of the equipment in MW? 84 MWh / 12 hours = 7 MW
What are two ways machines make work easier?
Machines make work easier because they help to increase productivity. An example of a machine is a forklift. Forklifts allow workers to move more materials at one time which lowers the amount of time it takes to move materials.
When the area over which a force is applied decreases what increases?
When the area over which a force is applied decreases, the average force applied over said area increases. In other words, the pressure (force/area) increases.
Pressure is a force defined as?
Pressure is a force defined as a push that acts over a certain area.
Is pressure a force?
Pressure is not a force. Pressure is force per unit area over which it is applied.
How pressure is mesured?
Measure the force being applied and divide by the area it is being applied over.
Force per unit area is termed?
Pressure is the force measured over an area
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is the pressure exerted by a piston if a force of 12N is applied over an area of 1.2m squared?
Pressure is force / area. Just divide the force by the area. The answer is in pascal.
What is the force caused by particles hitting a certain area?
Pressure. It is measured as a given force applied over a given area.
How much pressure is being applied If 30 N of force is exerted over an area of 20 m2 .?
If 30 N of force is exerted over an area of 20 m2 1.5 pascals of pressure is being applied.
What is the relationship between pressure force and volume?
Pressure is a force applied over an area. Volumes have internal pressures.
What is the relation between force and area?
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. p = F / A where:p is the pressure,F is the normal force,A is the area.
What is the amount of force exerted on a given area?
That is pressure. It is the force over an area applied to an object in a direction perpendicular to the surface.p = F / A where:p is the pressure,F is the normal force,A is the area.
