Bonus: Investigate whether the equilibrium can be maintained. The coefficient of static friction is

. Hint: The friction at

is pointing up, determine the ratio

at

in terms of the distance

where

is the distance between the normal force line of action and the top surface of the block. Determine the possible range of

and if there are any values of

so that

.
