square flexible foundation of width B = 2 m applies a uniform pressure of 17 kN/m? to the underlaying ground. Determine the vertical stress increase using at a depth of Im below the center using: a) 2:1 method b) M and N method c) Stress isobars LA

Problem #3 (33 points) The two 500-lb forces are parallel to the y axis and the P force is parallel to the z axis. If the allowable shear stress is 8 ksi, calculate the smallest permissible diameter of the solid shaft AE. Use the Maximum Shear Stress failure theory. 7 in P 7 in 7 in 7 in 4 in 6 in 4 in 500 Ib 500 Ib

Please kindly solve a,b,c and d... Please help me with all answers.... Urgent  Thank you

2. Find the induced stress at point B at depth 20 ft below the surface. The bearing pressure on the area is 400 psf. 40 ft 35 ft 70 ft
