F_A = 4.8 kN
F_B = 5.1 kN
F_C =1.6 kN
F_D = 1.9 kN
a = 4mm
b = 4.1 cm
c = 6.8 cm
d_s = 5 mm
d_t (effective) = 3mm
Assume:
∙ Bearing stress between threads of the bolt and the nut may be neglected
∙ Stress concentration effects may be neglected
∙ The force that the nut applies may be treated as a concentrated force.
∙ The nut may be treated as rigid.
∙ The forces applied to the nut and the shoulders of the bolt are distributed evenly around their perimeters
