Efficiency $\eta = \fracW_outQ_in = 1 - \fracQ_cQ_h$. Carnot efficiency (reversible): $\eta_max = 1 - \fracT_cT_h$ (temperatures in Kelvin).

For fixed-axis rotation: $\theta$, $\omega = d\theta/dt$, $\alpha = d\omega/dt$. Relationship to linear: $s = r\theta$, $v_t = r\omega$, $a_t = r\alpha$, $a_c = r\omega^2$. --- Fisica Para Ingenieria Y Ciencias Ohanian Vol.1 3ed Pdf

This is widely considered one of the best textbooks for Engineering and Science majors available in Spanish. It strikes a near-perfect balance between conceptual understanding and rigorous mathematical problem-solving. If you are an engineering student who needs to actually understand the "why" and "how" of physics—not just memorize formulas—this is an excellent choice. Efficiency $\eta = \fracW_outQ_in = 1 - \fracQ_cQ_h$
