Question

Side B now rests on a horizontal surface. If a horizontal force pointed to the left is applied at the top outer corner at E, what is the maximum force

that can be applied before the channel will tip? Weight remains 10 N. (Ignore slipping) (Assume the horizontal force from above is removed.) If the angle of friction for the channel is 30degrees, what is the maximum horizontal force that can be applied to the right at the midpoint of A?Where is the normal force located?
