Problem 19.4 A beam is made up from 3 plates, as shown, to serve as a support rail for a crane hoist in a factory. The beam spans 30 feet. The hoist is supported by a carriage, as shown. IF the system capacity is governed by the strength of the beam, determine the maximum loạd that can be lifted by the hoist. Take the allowable flexural stress in the beam to be 12 ksi. 30 feet 2.5 feet ½" x 4" plate %" x 10" plate ½" x 8" plate Crane hoist carriage

Methods to Determine Vertical Stress

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal component of the soil or the underground formations undergoes deformations or a tectonic shift. The amount of deformation depends upon the amount of load acting on the soil surface, which indeed, depends on the weight of everything present above the soil. Due to this, the underground soil element develops internal stresses which try to resist the tectonic changes.
