For some bending tests,the measured ovalisation of the pipe,unloaded after the test,was larger than the Offshore Standard OS-F101 [11] prediction for ovalisation at maximum bending strain.This may be due to the DNV Offshore Standard OS-F101 (2000) being valid for pure bending while ova...
Effectively isolate all coverage of the gap between pipe and stacked fins, hence improve heat dissipation effectively.Ultra-fit Heatpipe Consolidated to Maximize the Contact. The heatpipes are consolidated to maximize the contact among each others and also the GPU baseplate for the optimized heat dis...
[Note that for a pipe or cylinder, a representative segment of unit axial length may be used by replacing EI by Et3 / 12 (1 - v2 ) e ≈ I / ( R A) positive distance measured radially inward from the centroidal axis of the cross section to the neutral axis of pure bendingθ, x...

Charles Lucas Engineering clearly hoped to compete in Formula One races. The Lotus-Martin was completed in time for Roy Pike to enter the 1966 Boxing Day Formula Libre race at Mallory Park, and he finished third on a rain soaked track. The car's second appearance would have been the non-...
