How does reducing friction increase the mechanical efficiency of a compound machine?
Reducing friction in a compound machine helps minimize energy loss due to heat and wear, improving the overall mechanical efficiency. With less friction, there is less resistance to the movement of parts within the machine, allowing it to operate more smoothly and with less effort. This results in increased performance and reduced energy consumption.

If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
If there was no friction, mechanical advantage would remain the same since it is determined by the ratio of input force to output force. However, efficiency would increase because all the input energy would be transferred to the output without loss due to friction.
What does reducing friction increase?
Reducing friction increases the efficiency of movement and decreases the energy required to overcome it. This can lead to less wear and tear on surfaces in contact and prolong the lifespan of mechanical parts.
How does reducing friction increase the mechanical efficiency of a machine?
Reducing friction decreases the amount of energy lost as heat during machine operation. This allows more of the input energy to be converted into useful work, improving the mechanical efficiency of the machine. Lower friction also reduces wear and tear on components, leading to less maintenance and longer machine lifespan.
What can be done to increase the mechanical advantage of a wheel and axle?
To increase the mechanical advantage of a wheel and axle system, you can either increase the radius of the wheel or decrease the radius of the axle. This will result in a greater difference in radii, which enhances the mechanical advantage. Additionally, reducing friction in the system can also improve its overall efficiency.
When do we need to reduce friction?
Friction should be reduced when trying to increase efficiency, minimize wear and tear on surfaces, or improve the performance of mechanical systems. It is important to reduce friction in cases where it hinders movement or causes energy loss.
