Question 2) In the system given in the figure, a distributed load of w=36 kN/m acts on the rod AB of L=4 m length. The angle θ that the bar BC makes with the horizontal is θ=48°. The allowable normal stress for bar BC is σm= 221 MPa, and the allowable shear stress for pins at points A and B is τm=68 MPa. Bar BC has a rectangular section and the side length a of the section is given as a=34 mm. According to this; Question 2-A) Find the smallest b side length required for the bar section BC. (Write your result in mm.) Question 2-B) The connection type at point B is given in the figure next to it. Accordingly, find the smallest diameter required for pin B. (Write your result in mm.)

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.
