Consider the bar with total mass m =
and length L = 1m. The bar is uniform
in density, so consider the weight broken up
into 2 pieces: one on the left and one on the
right, proportional to the amount of mass
there.
(a) If m₁ = 2kg, what force at A is exerted
to maintain equilibrium?
(b) Find the minimum value of the mass m₁
required to cause of loss of contact at the
smooth wall A.
