Work:
In its technical sense, work is the product of force and distance, and work is done only when a force causes movement. We can see this by the formula:
Work = Force x Distance
We normally measure distance in feet or inches, and force in pounds or ounces. This allows us to measure work in foot-pounds or inch-ounces.
Example:
To find the amount of work done when a 500 pound load is lifted for a distance of 6 feet, we can use the formula:
= 500 X 6
= 3,000 foot-pounds
Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25. Compute the feedback ratio? Af = A / 1 + Aβ 25 = 50 / 1 + 50 β 1 = 2 / 1 + 50
