Two torsional springs, M = ku, are used to assist in opening and closing the hood of this truck. Assuming the springs are uncoiled (u = 0°) when the hood is opened, determine the stiffness k (N # m>rad) of each spring so that the hood can easily be lifted, i.e., practically no force applied to it, when it is closed in the unlocked position. Use appropriate numerical values to explain your result.
