Question

The allowable tensile stress for a 6.25mm diameter bolt with a thread length of 5.5 mm is 207 Mpa. The allowable shear stress of the material is 103 Mpa. Where and how will such a bolt be most likely to fail id placed in tension? (Assume threads are perfectly triangular and that the force is carried at the mean thread height.) Will the bolt most likely fail due to shearing of the threads or due to tensile failure of the bolt diamter

Answer 1

Answer:

The allowable tensile stress for a 6.25 mm diameter bolt with a thread length of 5.5 mm is 207 MPa. The allowable shear stress of the material is 103 MPa. Where and how will such a bolt be most likely to fail if placed in tension? (Assume threads are perfectly triangular and that the force is carried at the mean thread height.) O (A) at the root diameter due to tension O (B) at the threads due to shear (C) at the root diameter due to shear (D) at the threads due to tension
