Adding oil to the moving parts of machines can do that because it makes it smoother and takes the rust off of it.

What's the difference between blower and fan?
A blower is a machine for moving volumes of a gas with moderate increase of pressure. A fan moves large amounts of gas with low increase in pressure.
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 can increase friction on a moving object?
by slaiding friction increase
Why are there no machines that use energy with 100 percent efficiency?
From a practical standpoint there are no machines that use energy with 100% efficiency because all movement generates some friction and hence heat and loss of efficiency. Even electrons moving through superconductors generate minute amounts of heat. From a theoretical standpoint it's impossible to get 100% efficiency; all energy transformations increase entropy. Even if you could devise a machine with no friction, the process of converting energy from one form to another ALWAYS increases entropy. It's a result of the second law of thermodynamics. No machine can perform with 100% thermodynamic efficiency. The process used by any machine, be it steam, electric, horse drawn, wind, or whatever, can be reduced to a simple description of heat moving from a higher temperature to a lower temperature. The Carnot cycle provides a means to calculate the maximum theoretical efficiency possible. In reality, this maximum efficiency is NEVER achieved due to heat losses, friction, etc. Note that according to the Carnot cycle, 100% efficiency is impossible. The energy input to the machine can NEVER be entirely converted to useful work. Some of the energy is ALWAYS lost as heat to the surroundings.
how do insects increase the efficiency of gas exchange during strenuous activity?
No
How can you increase purchase efficiency?
You can increase your purchase efficiency by reducing the amount of dead stock or slow moving inventory items. This will lower your total inventory value, increasing purchase efficiency. "Stock Items Only Of Which You Have Need"

Cloud the pendulum be changed to increase the period of the pendulum?
Yes. You can increase the period by moving the pendulum to a location where the gravitational force is weaker.Alternatively, you can increase the effective length of the pendulum. The pendulum may be of fixed length, but you can still increase its effective length by adding mass to any point below its centre of gravity.Yes.

Why is the mechanical efficiency of most compound machines lower than most simple machines?
It is lower because compound machines have more moving parts that a simple machine does.
How do lubricants help to improve a machine's efficieny?
Lubricants help to improve the efficiency of a machine by allowing for a lessening of friction between moving parts. This causes those parts to remain cooler and have less wear and tear in the long run.
How do lubricants increase a machine's mechanical efficiency?
A pulley has a center axle around which it rotates. A rope passes over the pulley and is attached to the load. In an ideal pulley the work done in lifting the load is exactly the same as the energy expended. In a real pulley, because of the friction, we need to spend more energy in lifting the load. The additional energy is dissipated, i.e., wasted in the friction. Adding a lubricant to the shaft of the pulley reduces the friction and therefore increases the efficiency. A very thin layer of oil (lubricant) in between the moving and stationary parts can reduce friction very significantly.

Is a simple machine a vending machine?
No,because it has moving parts in it and a simple machine dose not have any moving parts
What machine has the most moving parts?
Most man- made machines have relatively low efficiency. For instance, a car or aeroplane is very noisy and will get very hot. This noise and heat is wasted energy and makes up a significant proportion of the total energy (fuel) input.
Why does the effective nuclear charge increase when moving down the first group on the periodic table?
As you go down the first group (or any group), you are adding protons and electrons. As you add more and more protons, the effective nuclear charge will increase.
