Consider the bar with total mass m = 20kg and length L = 1m. 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.
