| 1306. To H1/GLT. from Rm {William Robotham - Chief Engineer} /FWK. Rm {William Robotham - Chief Engineer} /FWK.14/JH.2.3.39. COIL SPRINGS. Will you please poundage test the coil spring FB.3826, which you have received from us. The Theoretical poundages at different deflections are as follows :- Load when compressed to 5.621" = 1848 lb. Load when compressed to 7.183" = 1380 lb. Rate 300 lb/in. Rm {William Robotham - Chief Engineer} /F.W.Kennington. | ||
