3. Extra Credit (15 pts.) A double-threaded screw (diameter 10 mm, pitch 2 mm) is used to adjust the position of a 500-kg block as shown. Show that it's possible to lower the block by turning the screw (that is, show that there isn't too much friction between the block and the incline). What minimum torque applied to the screw is required to lower the block down the incline? Assume a coefficient of static friction of 0.3 between all surfaces....
