When metal rusts, there are several problems that result. First, the rust itself is not as strong as the metal was before it rusted, and the rust often flakes off. Secondly, the shape of an object changes when it rusts. Rust does not occur with perfect uniformity everywhere so some sections are more rusted than others. Machine parts have to fit together accurately in order to do what they are designed to so, so when their shapes change, they no longer fit as accurately as they used to fit. Hence, a machine with rusted parts will not move smoothly.
What else can I help you with?
Why are ball bearing used in wheels?
Machine parts use ball bearings to reduce friction, making it easier to move the moving parts and producing less wear on the parts.
What are solar collectors a part of?
solar collectors are parts of all solar energy systems passive systems dont move pumps, fans, trackers are parts of active solar systems
How do Ocean Circulations develop?
it is developed when you have two parts of ocean whit diffrent temperature which drives the wother to move from hot regions to cold ones
What is true of a real machine that enables a person to move a heavy object with little applied force?
I'd go with simple machines. Specifically, probably a pulley (or pulley system).
why it is important to reduce friction at movable joint?
friction will resist smooth motion at a moveable joint so reducing friction allows joint to move freely
Does grease on machine parts create more or less friction?
Grease on machine parts reduces friction by providing a lubricating layer between moving surfaces. This helps to prevent wear and heat generation, allowing parts to move more smoothly.
How does lubricating a machine affect the output work from that machine?
Lubricating a machine reduces friction between its moving parts, allowing them to move more freely and smoothly. This can result in improved efficiency and reduced wear and tear on the machine, ultimately leading to increased output work by maintaining optimal functioning of the machine.
What means to move smoothly?
it means to move smoothly
Why adding oil to the moving parts of a machine can increase its efficiency?
Adding oil to the moving parts of machines can do that because it makes it smoother and takes the rust off of it.
What does hopelessly jammed mean?
A piece of machinery is jammed when parts that are supposed to move smoothly do not move at all, because something that does not belong in the machinery has gotten in the way. It is hopelessly jammed if it is jammed so badly that there is no hope of getting rid of whatever is jamming it to make it move smoothly again.
How does the shaft work in this machine?
The shaft in this machine rotates to transfer power from the motor to other parts, allowing them to move or function.
What is the function of the muscular sysytem?
the muscles in the body help the skeletal system as they help the body parts move very smoothly and flexiblely
What form of energy do the moving parts of a machine have?
The moving parts of a machine have kinetic energy, which is the energy associated with their motion. This energy is the result of work being done to make the parts move and is typically used to perform mechanical tasks within the machine.
What type of simple machine is in scotch tape dispenser?
The simple machine in a scotch tape dispenser is a wheel and axle. When you turn the wheel, it helps to move the tape smoothly out of the dispenser, making it easier to handle and use.
What is a machine that uses gas to move?
There are several:some rocketssome carssome lawnmowerssome airplanessome boatssome generators (they don't move far, but their engine parts move)
Why do you oil the chain on your bike?
to make it run smoothly, stop it from rusting and it makes it easier to pedal! If it isn't oiled or lubricated in any other way, all the parts that make up the chain will drag more as they move against each other, making pedalling harder. The chain will also wear out quicker. If it isn't oiled or greased the chain will eventually begin to rust, and rusty parts take even more power to get them to move against each other.
Why is the sewing machine often oiled?
Because it has lots of moving parts that has to be able to move easily.
