How do we decrease friction in machines?
You provide lubrication.
What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
Advantage and disadvantage of hydraulik machines?

What are advantages and disadvantages of using animatronics?
Advantage: machines usually have lower cost per hour than people Disadvantage: uncanny valley. People may find machines scary.
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.
What is disadvantage of friction?
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.

What are the advantage of the electronic voting machines?
The biggest disadvantage of electronic voting machines is the risk of security breach since it could be hacked by outsiders. There are many advantages including convenience, it is quick, and easy to use.
Why so helpful to reduce friction on simple machines?
Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.
What is the advantage or disadvantage of using ATM?
One advantage is that you don't have to go inside a bank.And one disadvantage of using the ATM is that you can not talk to the person, if the machine messes up.Using ATM machines has more advantages than disadvantages. ATM machines are like a daily staple which is used every day to make withdrawals and deposits without visiting the bank itself and standing in long queues. One of the diasdavantages is that ATM machines are becoming insecured and more prone to thefts and burglary.
Why noise is produced in machines?
Noise is produced in machines due to friction.
When is friction needed?
when machines are used
When friction is not needed?
when machines are used
Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
