Tension and Compression at a Cantilevered Joist, Rafter, or Beam

A cantilever is a joist, beam, or rafter that extends beyond its support, creating an overhang. For cantilevered beams, rafters or joists, the section extending beyond the support point experiences tension on the top side and compression on the bottom side when a load is applied. This is the opposite of the typical beam-bending scenario.
