Prior to digital computers there were electronic calculators, mechanical calculators, slide rules, abacuses, and counting tables. Slide rules were used by engineers into the 1970s (Keuffel & Esser’s manuals or The Slide Rule and Logarithmic Tables by J.J. Clark). The later problems in Timoshenko's Engineering Mechanics are orientated around logarithms to cut down the amount of computation for students. More involved calculations (say from meteorological observations) were just computed by offices of people with or without mechanical assistance
