- A high-strength bolt that passes through a steel plate is subjected to a tension force of P as shown in the figure. The hole in the metal plate has a diameter of D=17 mm which is slightly larger than the diameter of the bolt (d, = 12 mm) to allow for easy installation process. The plate has a thickness of t= 9 mm. The bolt head has a thickness of a = 9 mm and an outer diameter of dn = 24 mm. %3D Determine: A) the maximum value of P before the shear stress in the rod head exceeds Thot = 105 MPa. B) the maximum value of P before the punching shear stress in the support plate exceeds Tplate = 75 MPa.
