Suppose a body with weight W is pulled along a flat plane by a drag force which acts alongside a string fixed to the body. If the string creates an angle θ with the flat plane, then the drag force is F = μW μ sin θ + cos θ where the coefficient of friction is denoted by μ. Note that μ and W are constants. Determine such a θ for which F is minimum. Also evaluate that minimum value.
