The rocket shown in the figure below. is held stationary by the horizontal force, \( F_{x} \), and the vertical force, \( F_{z} \). The velocity and pressure of the exhaust gas are \( 7600 \mathrm{ft} / \mathrm{s} \) and \( 20 \mathrm{psia} \) at the nozzle exit, which has a cross section area of \( 60 \mathrm{in}^{2} \). The exhaust mass flowrate is constant at \( 21 \mathrm{lbm} / \mathrm{s} \). Determine the value of the restraining force \( F_{x} \). Assume the exhaust flow is essentially horizontal. \[ F_{x}= \]
