You have to build a box lifter, this will be made with a square threaded power screw. The power screw is 3 inches in diameter and 2 threads per inch. To improve the speed of raising and lowering the boxes, it must be with triple thread. The coefficient of friction of the screw and collar is 0.25, the diameter of the collar is 4 inches.Calculate:1. The depth of the thread, the width of the face, the average diameter, the root diameter, the pitch and its feed.2. The torque to increase the load and the efficiency of the screw.3. The speed of the motor (in rpm), if it is directly coupled to the screw and it is desired that the boxes rise at a speed of 30 inches/min.
Question 3 A single square thread power screw is to raise a load of 50 KN. A screw thread of major diameter of 34 mm and a pitch of 6 mm is used.

3) To provide a clamping force of 48,000 lb between two components of a machine (Tensile load, ignore bending), A set of six screws is used. The load is equally shared among three screws. Specify suitable standard screw, including grade of the material (Use Table 10.1 and 10.4 from the book to select the standard size screw. SAE Grade 7 type fasteners with UNC thread need to be used.). Clearly write down all the assumptions, and the details of the screw selected. Calculate the torque prescribed.
