The machine component from problem 2 (bar with hole and notches) undergoes variable loading from 42,500N to 45,000N. The part is made from 6061-T6 aluminum (S_u = 310 MPa and S_y = 275 MPa). The machined part requires a reliability of 95%. The large size results in a gradient strength factor of c_G=0.8 (see note c in Table 8.1). Calculate the safety factor. If the safety factor is less than one (i.e., shaft fails), find the number of cycles to failure.

3) The machine component from problem 2 (bar with hole and notches) undergoes variable loading
from 42,500N to 45,000N. The part is made from 6061-T6 aluminum (S_u = 310 MPa and S_y = 275
MPa). The machined part requires a reliability of 95%. The large size results in a gradient strength
factor of c_G=0.8 (see note c in Table 8.1). Calculate the safety factor. If the safety factor is less than
one (i.e., shaft fails), find the number of cycles to failure.

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).
