    A glider of mass 200kg (including pilot) is being pulled at constant speed into the air using a town rope connected to a winding motor on the ground. At a certain time the glider is in equilibrium when the angle of the tow rope to the ground is at 20 degrees and the tension in the rope is 7300N.
    a) draw a sketch of all the forces acting on the glider (tension, drag, weight and lift)
    b) calculate a value for the drag force and the lifting force on the glider (g=10m/s)
    c) identify two simplifying assumptions that have been made and dicuss the effects of each on the system of forces if these assumptions are not made

    I've drawn lift and weight opposite each other, drag perpendicular to the aforementioned forces and tension at an angle 20 degrees to the ground. As the glider is equilibrium, shouldn't lift and weight be equal, and drag and the horizontal component of tension be equal?

    Thanks for any help in advance.
