Having some trouble with this:
https://gyazo.com/0835bdaa8e01cb976765aac94555f6ef
I know how to show that at x_2 = -h the surface traction is zero, but I'm not sure how to show it's in equilibrium? Not sure how to get the forces to equate. Same problem with part (ii), not sure how to derive the forces.
Any help would be great, thanks
