Question:

A blade held in a brace is used to tighten a screw at A.

(a) Determine the forces exerted at B and C, knowing that these forces are equivalent to a force-couple system at A consisting of R = âˆ’(25 N)i + Ryj + Rzk and MRA = - (13.5 NÂ·m)i.

(b) Find the corresponding values of Ry and Rz.

(c) What is the orientation of the slot in the head of the screw for which the blade is least likely to slip when the brace is in the position shown?
