While using a pencil sharpener, a student applies the forces and couple shown.

(a) Determine the forces exerted at B and C knowing that these forces and the couple are equivalent to a force-couple system at A consisting of the force (2.6 lb)i + = Ryj(0.7 lb)k and the couple MRA = Mxi (1.0 lb Â· ft) âˆ’ j(0.72 lb Â· ft).k

(b) Find the corresponding values of yR and Mx.
