PICKETT N1010-ES CompositWood (D) USE OF SPECIAL SCALES ON COMMON SLIDE RULES ======================================================================== CI & DI Scales ************** These scales are reciprocal to the corresponding C & D ( = X ) scales: CI = 1/C ; DI = 1/D. They make an efficient way for (1) multiplication and (2) are useful in replacing division by multiplication. This may be also used to avoid re-setting of the slide, when the next number to proceed would be outside of the slide. Example (1): 12.3 * 4.56 = 12.3 / ( 1 / 4.56 ) = 56.09 ------------ Set 4.56 on CI scale opposit to 12.3 on D scale (»division« operation) and read the result on D scale under the right »1«. Example (2): 12.3 / ( 4.56 * 2.34 ) = 1.153 ------------ Set 4.56 on the C scale opposite to 12.3 on the D scale. Move the hairline to 2.34 on the CI scale (»multiplication« operation) and read the result on the D scale. CF & DF Scales ************** These scales are »folded«: CF = π * C ; DF = π * D. They begin at π and the »1« is nearly in the middle of the rule. Any setting of C or D is automatically set on CF and DF too; therefore they can be used for: (1) Multiplication and division in the same way as with C & D (2) For all calculations involving multiplication (or division) of π eg.: Diameter * π = Circumference. (3) Most important is the use of CF & DF to avoid re-setting the slide. If the next number to proceed would be outside of the slide, it can be made on the CF & DF scales! Example (2): 3.45 * π = 10.84 ------------ Set the hairline on 3.45 on D scale and read the result on DF scale. Example (3): 1 kg = 2.2 lb 3.4 kg = ? 5.6 kg = ? ------------ Set the 2.2 on the C scale opposit to the left »1« on the D scale. For 3.4 on D scale the result 7.48 is on C scale - but for 5.6 there is no C available: Read 5.6 on DF and the result 12.3 on CF scale. CIF & DIF Scales **************** These scales are reciprocal to the corresponding CF & DF scales: CIF = 1/CF ; DIF = 1/DF. Same is true, what is said above for CI & DI. (E) COMMON MARKS ON THE CURSOR ======================================================================== FAQ: **** "Why my cursor has 3 vertical lines: A long black one in the middle, a red one in the left upper half, and a red one in the right lower half? - And I have seen other marks too..." Answer: ******* When the black hairline is set (on C or D = X) on the DIAMETER, than the left red line shows (on B or A = X2) the AREA of the CIRCLE - or when the black line is set (on A or B = X2) on the AREA of the CIRCLE, than the DIAMETER can be read under the right red line (on D or C = X). Common is the relation between the middle and the upper-right hairline on the cursor for the CONVERSION 1 [kW] = 1.3596 [PS] on scales A/B. Sometimes this relation is with the left to the right hairline on C/D. MERCHAND SRs have often a shorter hairline left of the middle hairline to calculate the INTEREST-YEAR with 365 DAYS ( instead of 360 days ).
