(d) Determine the stress components x' and x'y' acting on the inclined plane using direct equilibrium.
(d) Determine the stress components σx' and τx'y' acting on the inclined plane using direct equilibrium. It is a 2- d block on the xy plane that is rotated up 25 degree from the horizontal on the right side or counterclockwise. It is cut on an inclined plane at a 75 degree angle from the left side of the horizontal clockwise. There is a normal stress in the y direction that is 7ksi and shear stress that points toward the upper right corner. There is also a normal stress in the x direction that is 15ksi. I know the answer for σx' = 15.96ksi and τx'y'=0.598ksi but I am having trouble doing the work for it as I keep getting the wrong numbers as the answer. Help is appreciated.
