The yield stress of H62 material can be found by referring to relevant standards σ_ S = 120MPa, the formula of allowable shear stress and allowable yield stress can be obtained according to the fourth edition of mechanics of materials:
Looking up relevant standards, we can find that the yield stress σ _ s of H62 material σ_s=120Mpa, and the formula of allowable shear stress and allowable yield stress can be obtained according to the fourth edition of Material Mechanics:
