Final answer:
The question involves calculating the tension in a cable and the reaction at a support for a strut in static equilibrium, using principles of force balance and torque.
Step-by-step explanation:
The student is asking about static equilibrium problems involving the tension in a cable and the reaction at a support for a strut that is subjected to different loads. These problems require an understanding of the physical concepts of torque, force balance, and the properties of solids under stress. For answering such questions, one would typically draw a free-body diagram, identify the forces acting (including weight and tension), apply the conditions for equilibrium (net force and net torque are zero), and solve the resulting system of equations for the unknowns: tension in the cable and the reaction at the support.
