A flanged bolt coupling consist of a 9 steel bolts evenly spaced around a bolt circle 300 mm in diameter and 6 bronze bolts on a concentric bolt circle 200 mm in diameter. Determine the sizes of bolt diameters required (steel and bronze) if the torque applied is 6 kN – m and without exceeding the stress of 60 MPa in the steel and 40 MPa in the bronze. The ratio of the diameter, dn / ds = 1/2. Use Gs = 83 GPa and Gp = 28 GPa. Draw the figure. Psl< Pb Rs Rb Db Ds

as per your policy, customer service from bartley stated since you took a incomplete question and answered it instead of questions that actually need answering.    you owe me my questions and not to only solve one question, kindly solve all 3. And when i end up switching to CHEG not only will i be posting this on my vlog and social media i will also be contacting BBB and i will make sure to find out whos the special kid behind answering and trolling me ((:   kindly answer all 3 , thanks

Summary/Conclusion Discuss the strengths of your design and how it met the specifications. Discuss your assumptions and why they are valid. Discuss what you might change about your design in a redesign effort. Format: The project should be presented as a design report using a word processor. Include any hand calculations in an appendix. More details will be provided. Choose to design either a slip-jaw or channel-lock pliers to last for 25 years of use by a professional. Use an appropriate tool steel for the pliers. Design for 95% male grip force. Use a minimum factory of safety of 2.50. Determine dimensions not given. Slip Jaw Pliers A= 9.00 inches B=1.00 inches C= ? D=1.25 inches H= 1.875 Inches D B A
