How does friction affect the energy in a closed system of moving parts?
Friction affects the efficiency of a system since two objects rub against each other. When this happens, there is created which reduces the energy in the system.
How does increasing the number of pulleys affect the ideal mechanical advantage and efficiency of pulley system?
Ideal mechanical advantage is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load.The MA of a pulley is equal to the number of supporting ropes.If the load is supported by one rope , the M.A of the system is 1. Efficiency is 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by two ropes , the M.A of the system is 2. But Efficiency is still 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by three ropes , the M.A of the system is 3. Efficiency is still 1 for ideal pulley ( No loss of energy due to friction) .And so on.Read more: How_does_increasing_the_load_affect_the_ideal_mechanical_advantages_and_efficiency_of_a_pulley_system
Does friction effect braking force?
Most certainly for without friction the braking system would fail no matter how much force was applied.
What are factors that limit the efficiency of a machine?
Friction is the most common factor affecting the efficiency of any machine.
How does an increase in the load force affect the efficiency of a pulley system?
it might be to heavy for the wheel to handle and it break as the rope
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.
What would happen to a pulley system if the load were increased?
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.

Rosa has designed a pulley system for a school science project She has determined that as the coefficient of friction increases the efficiency of the pulley decreases With a coefficient of friction?

Does water and dust affect the efficiency of the braking system if yes how?
Reduces friction which is what they need to work but they generate a lot of heat, light pressure applied off and on for a few taps dries them out pretty quick.
What is the effect of cracked diaphragm in transmission?
The effect of a cracked diaphram in transmission is that it reduces the efficiency of the system.
How did airplanes affect mailing?
Increased time efficiency and reach of the system.
