Question

A u-control airplane of mass m is attached by control wires of length L and negligible mass to the "pilot" who controls the lift provided by the wing FL. The wires control the plane's elevator or angle of attack. The plane's engine keeps it moving at constant speed v in a horizontal circle.

Find the magnitude of the force of tension T in the wires when the plane is flying in a circle at an altitude such that the wires make an angle θ with the ground. Remember that the wings can provide lift only in the direction perpendicular to their area, i.e. in a direction perpendicular to the wires. Think carefully before selecting the angle of your coordinate system. Use variables m, v, L, theta, and g in your answer.

Anyone give me some hints!:>
