Question:

In an automated manufacturing process, three holes are drilled simultaneously in an aluminum block as shown. Each drill exerts a 50-N force and a 0.100- N m ‹… couple on the block. Knowing that drill A rotates counterclockwise and drills B and C rotate clockwise (as observed from each drill), reduce the forces and couples exerted by the drills on the block to an equivalent wrench and determine

(a) The resultant force R,

(b) The pitch of the wrench,
