Find the magnitude of the reaction at A and the tension in the nail using (a) the con- cepts of two and three-force bodies (closed polygon method discussed in chapter 2). The nail is directly under point B and assume it can only take tension (vertical reac- tion) whereas at A the surface is sufficiently rough to resist horizontal movement. The distance AB is 250mm and the 85N force acts perpendicular to AB. (b) Check your answers by doing sum of the forces and moments. As always, include a FBD(s) and clearly label all variables used in your calculations. 85N Answer(s): в 250mm 60mm Find the magnitude of the reaction at A and the tension in the nail using (a) the con- cepts of two and three-force bodies (closed polygon method discussed in chapter 2).
