How can we reduce friction in different machines?
Friction in machines can be reduced by using lubricants, such as oils or greases, between moving parts to create a smooth surface. Using materials with low friction coefficients can also help minimize friction in machines. Proper maintenance and regular cleaning of machine parts can prevent build-up or debris that may increase friction.
What machines are affected by friction?
All machines that have moving parts are affected by friction. Friction occurs when two surfaces rub against each other, which can cause wear and tear on the machine's components over time. In some cases, friction can reduce the efficiency of a machine by converting some of the energy into heat.
When does friction need to be reduced?
Friction needs to be reduced when trying to increase the efficiency of machines or decrease wear and tear on components. It is also important to reduce friction in situations where smooth movement or minimal heat generation is required.
Does friction reduces the efficiency of machines due to production of heat?
Yes, friction can reduce the efficiency of machines because it produces heat which leads to energy loss. This heat energy is not useful for the intended purpose of the machine, resulting in a decrease in overall efficiency. Minimizing friction through lubrication or using smoother materials can help improve efficiency.
What is machines that experiences friction called?
Machines that experience friction are simply called frictional machines or machines subject to friction. Frictional forces resist the motion or relative motion of surfaces in contact, causing resistance and heat generation in the process.
Why does friction reduce the mechanical advantage in machines?
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.

Why is machine heated up when it runs for sometime?
Machines heated up due to the friction caused due to their running internal parts. That's's why machines are oiled or greased to reduce friction and to produce less heat
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
Why machines are applied with grease?
It's to reduce friction (and thus heat) generated while the machine's parts are moving.

Why is oil used in many large machines?
Oil is used as a lubricant in many large machines in order to reduce the friction between two or more moving parts.
How are machines made?
As with most modern machines, they are made in factories.
How can you make machines more efficient?
Reduce or remove friction. Ensure that the energy going in is not wasted due to unnecessary work or heat.
Why are tools and machines coated with greases?
The grease is there to lessen friction between two metal parts. Without grease the moving parts would heat up due to the friction.
When does friction need to be reduced?
