L AND 6 5. The following data apply to the C-clamp of Fig. 12-7. American Standard Threads 13 threads per inch (single-threaded) Outside diameter - in, Root diameter = 0.4001 in. Root area = 0.1257 in? Coefficient of thread friction = 0.12(f) Coefficient of collar friction - 0.25 (-1) Mean collar radius - 0.25 in. Load W = 1000 lb Operator can comfortably exert a force of 20 lb at the end of the handle. (a) What length of handle, L, is needed? (6) What is the maximum shear stress in the body of the screw and where does this exist? (c) What is the bearing pressure P on the threads? B ЕВ Fig. 12-7
