Fasteners and Design of Non Permanent Joints

Fasteners are described as mechanical components used to join or assemble two or more pieces of materials. The fasteners are used in various machines or structures based on their suitability to produce non-permanent, semi-permanent, and permanent joints.

to ensure that there is a safety factor of 2 with regards to any slippage, if you are using:
a) bolts, A, C, G, and I.
b) bolts A, B, C, D, F, G, H, and I.
Would using bolts B, D, F, and H provide a greater allowable load? Explain why.

I keep getting this one wrong. For T1, I did 370/cos(30) = 427.24 lb tension , and -427.24 x cos(30)= -370. I also tried T1=820, and T2=-710.14, which was not correct as well. Thank you for your help on these two parts
Q.1 Design a compression coupling for a shaft to transmit 2000 N-m. The allowable shear stress for the shaft and key is 50 MPa and the number of bolts connecting the two halves are 6. The permissible tensile stress for the bolt material is 90 MPa. The coefficient of friction between the muff and the shaft surface may be taken as 0.3.

The figure shows a section of a large coupling. Each bolt in this joint is subjected to cyclic load fluctuating between 0 and 13 kN. The members are made from steel. The members have equal thicknesses and total length of members is L=37 mm. Each bolt is initially tightened carefully to 78% of proof load. The bolt is to be Metric grade 5.8 M12x1.75 (coarse-pitch series). The threads has been manufactured by rolling and reliability for bolts is 95%. Calculate the stiffness of the bolt (in kN/mm).

Problem 17 A joint shown has the basic layout shown in the diagram below. (All dimensions on the diagram are in inches.) A single pin of diameter 0.5 inches (A = 0.2 in2) holds together the yoke and bar as shown. The material has an ultimate strength in tension of 80 ksi, and an ultimate strength in shear of 45 ksi. The load P has a value of 10000 lb. By examining the shear stress in the pin, the normal stress in the yoke, and the normal stress in the bar, find the overall factor of safety for the joint.
