A blade held in a brace is used to tighten a screw at A.
Chapter 3, Problem 3.123(choose chapter or problem)
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 \(\mathbf{R}=-(30\mathrm{\ N})\mathbf{i}+R_{y} \mathbf{j}+R_{z} \mathbf{k}\) and \(\mathbf{M}_A^R=-(12\mathrm{\ N}\cdot\mathrm{m})\mathbf{i}\). (b) Find the corresponding values of \(R_y\) and \(R_z\). (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?
