The pin-connected bar system in Figure P14.3 is stretched \(1 \mathrm{in.}\) horizontally and connected to the pin support 4. Determine the horizontal and vertical components of force that the support must apply to the bars. Area of bar \(1=2 \mathrm{in} .^{2}\), area of bar \(2=3 \mathrm{in} .^{2}\), and \(E=30,000 \mathrm{kips} / \mathrm{in} .^{2}\). \(K_{2 x}\) and \(K_{2 y}\) are stiffness coefficients.
