las. Col-umn (and most other engineering) formulas can be representedgraphically. To represent Rankines formula for flat-ended mild-steel columns, P 50,000 A 1 + 36,000 we first substitute different values of Z h- v in the formula, andsolve for P h- A. Thus we find, when l^r = 40, P - A =… … lOO Piff. 48. 2 CO 300 off vertically from the points on the line, we get a series of ])ointsas a, 1j, c, etc.; and a smooth curve through the points a, b, c, 105 96 STRENGTPI OF MATERIALS etc., represents the formula. Such a curve, besides representingthe formula to ones eye, can be used for…
