What is the formula of efficiency?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.

What are two things affected by friction?
There are two main factors that will influence the total amount of friction: 1) the roughness of the surfaces (or the “coefficient of friction”) and 2) the force between the two objects. In this example, the weight of the object combined with the angle of the tray will change the force between the two objects.
How can we measure the efficiency and effectiveness of managers performance?
Effective management means; reaching goals in an efficient manner using less amount of resources. Management performance and effectiveness is measured by; Amount of Profit or Surplus. The rate of Productivity.
How do you measure effectiveness?
13 ideas on measuring employee effectiveness
- Management by objectives. This is probably the most common way to measure employee performance.
- Use rating scales.
- Ask staff to rate their own job satisfaction.
- Track digital trails.
- Team performance.
- Peer appraisals.
- External evaluators.
- Quantity and quality.
Why is the machine not possible in the real life?
Answer. In practice however no machine is perfect because some part of the work done on a machine is always used up or wasted in overcoming the friction between the moving parts of the machine. If a machine is 80% of the work input to the machine is obtained as the useful work output. …
How do you use efficiency?
“We have to work hard to achieve maximum efficiency.” “The new machines increased efficiency in the factory.” “The broken machine reduced efficiency.” “The managers want to measure the efficiency in the factory.”
How is effectiveness and efficiency measured?
Organizational performance = effectiveness x efficiency; Total asset turnover ratio measures the ability of a company to use its assets to efficiently generate sales; therefore it can be treated as efficiency. As a result, overall performance can be measured by quantifying the efficiency and the effectiveness.
How do you measure efficiency of processes?
Process cycle efficiency of an entire process is calculated by dividing the total waiting time by the total process cycle time.
Which is not affected by friction?
Answer: Velocity ratio is not affected.
Which is the most efficient machine?
bicycle
How do you explain efficiency?
What Is Efficiency? Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output. Efficiency requires reducing the number of unnecessary resources used to produce a given output including personal time and energy.
Is it possible to make a perfect machine in our daily life?
Answer. The definition of a perfect machine states that a perfect machine should be 100% efficient which means the 100% of the energy input should be transformed into work output. For these reasons,we cannot expect perfect machines in the real life situations.
