To quickly assess the difficulty of the text, read a short excerpt:
If deflections are taken on one side only, i. E. , without reversals of M, the requisite closeness in (3 will be attained when sin /3 tan 2 I OOO 500 roughly = o. Oo 060. This corresponds to /3 = 0. 00060/0. 0174 = o. O35 roughly = 2'. 26 The Telescope-Mirror-Scale Method. But it is more convenient to have the requisite closeness expressed in term...s of M A 1 MB'. Now, nearly enough when /3 is very small, AA' = BB'=OA tan/3=OA sin /3 = o. Oo 060 500 = 0. 30 mm. , and also MA' MB' =A A' -\- A ' = 2 OA tan /3 0. 60 mm. Hence, the requisite closeness in MA' MB' without reversals is 0. 6 mm. If reversals of deflections are taken, giving d on one side and d^ on the other, the corrected deflection is \d\-\-d-L sin /3 tan 2 qp sin 2 j8 -}- sin /3 tan 2(f sin 2 @\ 2 L 2 2 J = JL(4+4 J )_ sin 2 /3. 2 2 Hence the requisite closeness will be attained when sin 2 /3' = o.
