What else can I help you with?
If tight scissors have an efficiency of 50 percent half of your effort is wasted due to what?
It is due to friction.
What factor prevents a machine from operating at 100 percent efficiency?
Friction is one factor that prevents a machine from operating at 100 percent efficiency. Some energy is lost as heat due to friction between moving parts, which reduces the overall efficiency of the machine.
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 a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
What do you mean by the efficiency of a simple machine is 85 percent?
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.
What would a machine that had 100 percent mechanical efficiency be called?
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
Why is is that is impossible to have a 100 percent efficiency?
It is impossible to achieve 100 percent efficiency due to various factors such as friction, heat loss, and energy conversion losses. These factors result in some amount of energy being wasted in any process, making perfect efficiency unattainable.
Why is mechanical efficiency always less than 100 percent?
That simply means that some energy is lost, due to friction and other causes.
How does the revoshift friction system enhance the performance of a bicycle?
The revoshift friction system enhances a bicycle's performance by allowing for smooth and precise gear changes, resulting in improved control and efficiency while riding.
How does friction effect effiecency?
Friction reduces efficiency by converting some of the energy input into heat. This results in a loss of energy, making the system less efficient. Minimizing friction through lubrication or using materials with lower friction coefficients can improve efficiency.
What limits the efficiency of machine?
friction
