A horizontal aluminum rod 4.8 cm in diameter projects 5.6 cm from a wall. A 1200 kg object is suspended from the end of the rod. The shear modulus of aluminum is 3.0 ? 1010 N/m2. Neglect the rod's mass.
(a) Find the shear stress on the rod. (N/m2)
(b) Find the vertical deflection of the end of the rod. (m)
