Compare the primary dimensions of each of the following properties in the mass-based primary dimension system (m, L, t, T, I, C, N) to those in the force-based primary dimension system (F, L, t, T, I, C, N): 

(a) Pressure or stress;

(b) Moment or torque; 

(c) Work or energy. Based on your results, explain when and why some authors prefer to use force as a primary dimension in place of mass.
