Instead of using the system shown in Figure.a to raise the mass m2, an engineer proposes to use two simple machines, the pulley and the inclined plane, to reduce the weight required to lift m2. The proposed design is shown in Figure.b. The pulley inertias are negligible. The available horizontal space limits the angle of the inclined plane to no less than 30°. Suppose that the friction between the plane and the mass m2 is negligible. Identify the equation to determine the smallest value m1 that can lift m2. (The answer should be a function of m2 and θ.)
