I need it handwritten and all the parts I'll rate but pls all and correct

Extracted text: Question (1) power screw has single square threads. It has a major diameter of 36 mm and a pitch of 6 mm. The coefficient of friction for the threads is 0.13 and that for the collar is 0.1 which has an effective diameter of 90 mm. This power screw is required to raise a load of 70 kN at a screw rotational speed of 2 revolutions per second. Circle the correct answer in the following: A
