Extracted text: A flanged bolt coupling consist of six 10 mm. diameter steel bolts on a bolt circle 300 mm. in diameter, and four 10 mm. steel bolts on a bolt concentric bolt circle of 200 mm. in diameter. (a) Determine the torque applied (N-m) if the shearing stress is 60MPA in the bolts. (b) If the torque capacity increased to 8 kN-m, determine the number of bolts of 10 mm. diameter on the 300 mm. bolt circle of the coupling.
