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
The wheels and gears of a machine are greased in order to decrease?
Friction.
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.
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.
Does an ideal machine have friction?
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
What is three ways friction can harm you?
Causes wear and tear of machine parts.Burning of tyreswarming of hands
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.
What is the effect of friction on a machine?
Friction makes a machine less efficient by wasting energy.
What describes the relationship between friction and IMA for a simple machine?
An ideal machine has no friction. -Nn
What can reduce a machine's efficiency?
A. By decreasin the work inut to the machine without increasing output B. By reducing losses due to friction C. By increasing the ork ouput of the machine wihout increasing input D. All of the above D. ALL OF THE ABOVE
How does friction impact the amount of mechanical energy produced by a machine?
Friction in a machine can reduce the mechanical energy produced by increasing the amount of energy lost as heat. Friction between moving parts causes resistance, which converts some of the mechanical energy into thermal energy. Minimizing friction through lubrication and proper maintenance can help increase the efficiency of a machine and maximize the amount of mechanical energy it produces.
How does friction effect effiecency?
If there is more friction with a machine, efficiency is less.
What limits the efficiency of machine?
friction
How do you reduce the friction in a machine?
Oil it
