A rigid horizontal rod of length 2L is fixed to a circular cylinder of radius R as shown in the figure. vertical forces of magnitude P are applied at the two ends as shown in the figure. The shear modulus for the cylinder is G and the Young’s modulus is E.
The vertical deflection at point A is
(a) $\frac{PL^3}{(\pi R^4G)}$
(b) $\frac{PL^3}{(\pi R^4E)}$
(c) $\frac{2PL^3}{(\pi R^4E)}$
(d)$\frac{4PL^3}{(\pi R^4E)}$
