A horizontal bracket ABC consists of two perpendicular arms AB of a length 0.75 m and BC of a length 0,5 m. The bracket has a solid, circular cross section with a diameter equal to 65 mm. The bracket is inserted in a friction less sleeve at A (which is slightly larger in diameter), so it is free to rotate about the r0 axis at A and is supported by a pin at C Moments are applied at point C M{=1.5 kN -m in the x direction and A/3 = L0 kN-m acts in the — z direction. Considering only the moments Mxand M2, calculate the maximum tensile stress t, the maximum compressive stress crc* and the maximum in-plane shear stress Tmax at point />, which is located at support A on the side of the bracket at mid-height
A long re Lai nine: wall is braced by wood shores set at an angle of 30° and supported by concrete thrust blocks, as shown in the first part of the figure. The shores are evenly spaced at 3 m apart. For analysis purposes, the wall and shores are idealized as shown in the second part of the figure. Note that the base of the wall and both ends of the shores are assumed to be pinned. The pressure of the soil against the wall is assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the walls is F = 190 kN. If each shore has a 150 mm X 150 mm square cross section, what is the compressive stress
