SITUATION. The cable of a suspension bridge shown in the figure below runs over a frictionless pulley on the top of each of the towers at A and B and is fixed to anchor blocks at D and E. The cable carries a uniform horizontally distributed load of w = 160 kN/m. The permissible working stress of the gross area of the cable, including voids, is 800 MPa. Unit weight of concrete is 23.4 kN/m³. For this problem, L= 400m, S = 40m, H = 60m, a = 45°.

A circular footing of (225 kPa) is resting on a dry soil with a concentrated load (P) which act at the edge of the footing as shown in figure below. Find the maximum value of P that make the increase in stress at soil element (A) which located 2m under the center of the footing equal to (114 kPa) (use related equations) D=2m N.G.S G=2.62 e=0.43 Soil element A Select one or more: O a. The Concentrated load is about 730 kN

2. Solve the following problem Determine the maximum torque T that can be resisted by two shafts with a circular section of outer diameter of 100 mm. For the first shaft, the section is solid (no holes). For the second shaft, the section is hollow with an inner diameter of 75 mm. Use an allowable shear stress Tallow = 100 MPa and provide a drawing of the shear stress distribution on both sections.
