Σελίδα 163 - Fig. 49. We will solve this problem partly graphically and partly by calculation. The first step is to find how fast the crank pin D is moving. For one turn of the crank, D travels through a distance equal to the circumference of a circle whose radius is R, that is, a distance of 2'ffTi.
Σελίδα 3 - An Improper Fraction is one whose numerator is equal to, or greater than, the denominator; as, f, f.
Σελίδα 41 - To divide by 10, move the decimal point one place to the left. To divide by 100, move the decimal. point two places to the left, and so on for other powers of 10.
Σελίδα 5 - When the numerator is less than the denominator, the value of the fraction is less than 1. 5th. When the numerator is equal to the denominator, the value of the fraction is equal to 1. 6th. When the numerator is greater than the denominator, the value of the fraction is greater than 1.
Σελίδα 76 - In any proportion, the product of the means is equal to the product of the extremes.
Σελίδα 41 - To multiply by 10, move the decimal point one place to the right, annexing a zero if necessary.
