Question

A bracket is fastened to the steel structure by means of six identical bolts as shown in figure. Assume the following data: P = 50 kN; l = 250 mm; l1 = 300 mm; l2 = 200 mm; l3 = 100 mm; Neglecting shear stress, determine the size of the bolts, if the maximum permissible tensile stress in any bolt is limited to 100 N/mm2.

Step 1

Since there are six identical bolts, the total force P (50 kN) will be equally distributed among them. Therefore, the force acting on each bolt (F) can be calculated as: F = P / 6 F = 50,000 N / 6 F = 8,333.33 N Show more…
