For a bolted assembly with 8 bolts, the stiffness ofeach bolt is k_b = 1.1 N/mm and the stiffness of themembers is k_m = 2.8 N/mm at each bolt location. Thejoint is subject to occasional disassembly formaintenance and should be preloaded accordingly (to75% of the proof stress). Assume the external load isequally distributed to all the bolts. It has beendetermined to use M6 × 1 class 5.8 bolts with rolledthreads.Determine the maximum safe working load that bothlimits the stress in the bolts to be below the proofstress and ensures that the members do not come outof compression.Express your answer in units of kilonewtons.

Question is solved below Explanation:To find the maximum safe working load for the bolted assembly,…

Answered: For a bolted assembly with 8 bolts, the…
