What else can I help you with?
The wheels and gears of a machine are greased in order to decrease?
Friction.
What are the causes of sliding friction?
For example the cause of sliding friction of two materials is when the stress between the Materials is not equal to zero
Are the friction losses of the machine linear in induction motor electrical machines?
yes
What causes saturation in a welding transformer?
what causes saturation in welding machine
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
Is it true or false that friction reduces the efficincy of a machine?
True. Friction causes resistance within a machine, leading to loss of energy in the form of heat. This decrease in efficiency can result in the machine requiring more energy input to overcome friction and perform its intended task.
What is three ways friction can harm you?
Causes wear and tear of machine parts.Burning of tyreswarming of hands
What an example of a machine in which friction is both an advantage and a disadvantage?
A car is an example of a machine where friction can be both an advantage and a disadvantage. Friction between the tires and the road allows the car to accelerate, brake, and turn smoothly, providing traction. However, friction also causes wear and tear on the tires and causes the engine to work harder, leading to decreased fuel efficiency.
What is an obstacle to 100 efficiency for a real machine?
Friction is a common obstacle to achieving 100% efficiency in a real machine. Friction causes energy to be lost as heat, reducing the overall efficiency of the machine. Additionally, imperfections in materials, wear and tear, and other factors can also contribute to inefficiencies.
How does friction affect the work of a machine?
Well, if, for example, you had interlocking gears, the friction would slow down the speed of how they turn. Friction also causes heat, so too much friction could make a computer or a more advanced machine, melt inside. I think that DEFINETELY affects the work of a machine.
How does friction reduce the efficiency of machines?
Friction is cased by parts of the machine rubbing past one another. When this happens the parts tend to stick to each other which slows down the machine and heats up the parts. Thus the energy used to drive the machine is diverted from the purpose for which the machine was constructed and the machine becomes less efficient. To reduce friction and make the machine more efficient, lubricants (eg oil) are used to make sure that parts that come into contact can slide past one another more easily. -------------------------------------------------------------------------------- Friction causes machines to slow down, and heat up. effecting efficiency negatively first off excess causes a decrease in speed increase in wear on parts. Also friction causes heat which causes metals to expand. For optimal mechanical efficiency, friction is the enemy. ------------------------------------------------------------------------------------ Friction decreases efficiency. This is because when there is friction, heat is created. Therefore some energy is lost in the form of heat.
Why is friction between moving parts of a machine undesirable?
Friction between moving parts of a machine leads to energy loss in the form of heat, which can cause overheating and reduce the efficiency of the machine. It also causes wear and tear on the parts, leading to increased maintenance and replacement costs. Additionally, excessive friction can impact the accuracy and performance of the machine.
Does friction reduce efficiency of a machine?
When a machine is running at 100 % efficiency there is no loss of energy anywhere. That means the machine is running silently and if turned off will continue to run without stopping. In the real world there is sound and there is friction. Both sound and friction are examples of less than perfect efficiency
What force causes a difference between the ideal and the mechanical advantage Of the same object?
The force required to overcome friction between parts of a machine or device causes a difference between the ideal and mechanical advantage of the object. Friction reduces the efficiency of a machine by causing energy losses, making it harder to achieve the theoretical ideal advantage.
Does an ideal machine have friction?
No, an ideal machine is usually considered to be frictionless to simplify calculations and convey fundamental concepts. In reality, all machines have some level of friction, which can reduce efficiency and introduce energy losses.
How does friction impact the amount of mechanical energy produced by a machine?
Well friction is the opposing force to any object who is doing work against another. So the force needed to overcome friction costs more energy than required thus decreasing efficiency of the machine.
Why it is important for you to reduce friction on compound machine?
Reducing friction on a compound machine is important because it helps improve the efficiency of the machine by minimizing the energy lost due to friction. Lower friction also translates to less wear and tear on the machine's components, ultimately extending its lifespan and reducing maintenance needs. Additionally, decreased friction can enhance the overall performance and precision of the machine's operations.
