Shear forces are forces that tend to cause a beam to slide along its own axis. Without shear reinforcement, concrete beams are susceptible to diagonal tension cracks, which can cause the beam to fail.<\/p>\n<p>The angle of the diagonal tension cracks in an R.C.C. beam not provided with shear reinforcement is approximately 45\u00c2\u00b0 to the horizontal. This is because the shear force causes the concrete to be in tension on the diagonal, and the concrete is strongest in tension when it is loaded perpendicular to its fibers.<\/p>\n<p>The other options
