It is calculated by dividing the force applied by the area over which it is applied.<\/p>\n<p>The shear stress at which a beam will fail depends on a number of factors, including the material it is made of, its shape, and the load it is carrying. In general, however, most beams will fail if the shear stress exceeds 20 kg\/cm2.<\/p>\n<p>Option A (10 kg\/cm2) is too low. Most beams will not fail if the shear stress is below this level.<\/p>\n<p>Option B (15 kg\/cm2) is a possibility.
