Efficiency η is the ratio of input work over the output work.
When discussing engines the ratio of output work to input work expressed as a percentage is called blank?
the ratio of output work divided by input work. Efficiency is often expressed as a percent with a perfect machine having 100 percent efficiency. You can improve efficiency by decreasing friction.
What is the ratio of the output work to the input work called?
The ratio of the output work to the input work into the machine is called efficiency .
What is the ratio of output force to input force?
The ratio of output to input force magnitudes for any simple machine is called its mechanical advantage (MA) .
Which refers to the ratio of output?
efficiency refers to. The ratio between inputs and outputs (i.e and efficient firm maximizes output per unit of input)
What is the formula for ratio of output to input?
Productivity: ratio of outputs (goods and services) divided by the inputs (resources, such as labor and capital) Output (goods and services) Productivity = Input (labor, capital, management) Improving Productivity: -improving efficiency – inputs while keeping output constant – outputs while keeping inputs constant ...
What is the ratio of output to input?
Productivity is defined as the ratio of output to input(s).
Is the ratio of work done over work input?
Efficiency can be expressed as the ratio of useful work output to total work input.
Which refers to a ratio of output force to input force of a machine?
Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.
What is the force applied to overcome resistance?
| A B | resistance force force applied by the machine to overcome resistance | work input work done on the machine | work output work done by the machine | work force x distance |
|---|
What is a moving inclined plane called?
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. ... The wedge can be considered a moving inclined plane or two inclined planes connected at the base.
What is output work divided by output force?
output distance. one way to determine this is to divide output work by output force. joule.
Which of the following terms is a measure of efficiency by which we calculate the ratio of output to input?
Productivity . Productivity –a ratio of production output to the input required to produce it–is one measure of production efficiency. Productivity is defined as a total output per one unit of a total input.
Which refers to the ratio of output work of a machine expressed as a percent?
Efficiency is the ratio of work output to work input. It is expressed as a percent. A perfect machine would have an efficiency of 100 percent.
What is the ratio of input?
Ratio of output to input is an objective measure of sales force performance that incorporates common ratios used to evaluate salespeople.
Is the ratio of output to any one class of input?
“ Productivity is an aggregate measure of the efficiency of production; it is the ratio of output to inputs i.e. capital, labor, land, energy and materials”.
