QUESTION 1: EPICYCLIC GEAR AND GEAR TRAINS An epicyclic gear train has a sun wheel with 24 teeth, and two planetary wheels of 46 teeth each, The latter mesh with the internal teeth of a fixed annulus with 116 teeth. The input shaft, carrying the sun wheel, transmits \( 4,5 \mathrm{~kW} \) at \( 280 \mathrm{r} / \mathrm{min} \). The output shaft is connected to an arm L that carries the planetary wheels. Calculate the speed of the output shaft.

Prequnta 3 (4 puntos) Calcular la variación de la energia interna de un bloque de hielo de 520 g que se se encuentra \( 0{ }^{\circ} \mathrm{C} \) y a presionn atmostérica, so funde y luego se calienta a \( 4{ }^{\circ} \mathrm{C} \). Densidad del hielo \( 0.917 \mathrm{~g} / \mathrm{cm}^{3} \), calor latente de fusión \( 3.34 \times 10^{5} \mathrm{~J} / \mathrm{kg} \), densidad del agua a \( 4{ }^{\circ} \mathrm{C} \) es \( 1 \mathrm{~g} / \mathrm{cm}^{3} \).
