2. A 30-mm bolt with an initial tension of 35 kN is subjected to several types of stresses during initial tightening or due to screwing up forces. If the bolt has a core diameter of 25.7 mm and considering 5 threads are already engaged with the nut, calculate the shear stress across the thread and the crushing stress between the threads. Assume 3.5 mm as the width of the thread section at the root.
