$(5)/(196)$ The heavy$-$lift helicopter is flying at constant

speed in level flight and is transporting a uniform

pole of length l and mass $\backslash$rho per unit length. The

pole is secured by a short cable at A and assumes

the constant angle $\backslash$theta with the vertical due to air

pressure. If air pressure produces a force p per

unit of length of the pole normal to the pole, de$-$

termine an expression for the angle $\backslash$theta $.$ Prove that

the short cable must be in line with the pole.
