Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.

What is the difference between actual machanical advantage and ideal machanical advantage?

Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.

What is the opposite of mechanical?

The opposite of mechanical (by machine) could be biological or natural.The opposite of mechanical (perfunctory, without thought) could be conscious, considered, or thoughtful.Where mechanical has the connotation automatic, the opposite would be manual.


Can any pulley have a efficiency over 100?

No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.


What is theoritical mechanical advantage?

The theoretical mechanical advantage is the ratio of the input force to the output force in a simple machine without accounting for energy losses due to friction or other factors. It represents the ideal mechanical advantage that a machine could achieve under perfect conditions.


What energy that put the amount of work machine?

The energy required to perform work in a machine is typically sourced from a power input, which could be electricity, fuel, or some other form of energy input. This energy is converted by the machine into mechanical work through various mechanisms such as electrical motors, combustion engines, or hydraulic systems. The efficiency of the machine determines how much of the input energy is successfully converted into useful work output.


How can a machine's efficiency be calculated?

Machine efficiency can be calculated by dividing the useful output of the machine by its total input, and then multiplying by 100 to express it as a percentage. Useful output could be output energy, work done, or products manufactured, while total input includes energy or fuel consumed. The formula for efficiency is: Efficiency = (Output/Input) x 100%.


How do you calculate the efficiency of an electrical mechanical system?

To calculate the efficiency of an electrical mechanical system, you would divide the useful output (mechanical work done) by the total input (electrical energy supplied). The efficiency formula is: Efficiency = (Useful output / Total input) * 100%. This calculation gives you the percentage of input energy that is successfully converted into useful output in the system.


Does a bigger wheel increases the efficiency of the machine in the wheel and axle?

Generally automobiles are designed with optimum size wheels. Changing the diameter is unlikely to increase efficiency, and could well have the opposite effect.


What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?

If friction is reduced through the use of oil or another means, the mechanical advantage of the machine would typically increase. This is because less energy is lost to friction, resulting in more efficient operation and a greater output force compared to the input force.
