Desglose Temático y Posibles Respuestas Razonadas

A continuación, analizamos los tipos de preguntas más frecuentes en el test global de mecánica 1, con ejemplos de respuestas correctas y su justificación.

Bloque D: Caso práctico global

Enunciado típico: Se tiene un motor a 1450 rpm con polea de 50 mm. Conecta mediante correa a una primera polea intermedia de 200 mm, solidaria a un engranaje de 25 dientes que acopla a otro de 125 dientes sobre el eje de salida.

Preguntas:

1. Velocidad del eje intermedio.
2. Relación total.
3. Velocidad final.
4. Par final si el motor entrega 10 Nm (rendimiento 90%).

Soluciones paso a paso:

1. Tramo poleas: N_intermedio = (50*1450)/200 = 362.5 rpm
2. Relación engranajes: 25/125 = 0.2
3. N_final: 362.5 * 0.2 = 72.5 rpm
4. Relación total: (50/200) * (25/125) = 0.25 * 0.2 = 0.05 (reducción enorme)
5. Par final: Par_entrada = 10 Nm; Relación = 1/0.05 = 20; Par_salida teórico = 200 Nm; con rendimiento 0.9 → 180 Nm

Respuestas finales:
N_intermedio = 362.5 rpm; Relación total = 1:20 (o 0.05); N_final = 72.5 rpm; Par final = 180 Nm

Estrategia de estudio para aprobar sin depender solo de las respuestas

1. Practica con ejercicios similares: Si solo memorizas respuestas, el día del examen cambiarán números o figuras. Domina la fórmula i = D1/D2 y N1D1 = N2D2.
2. Construye mecanismos caseros: Con Lego Technic, impresoras 3D o incluso cartón, ver el movimiento real fija conceptos.
3. Realiza el test en tiempo real: Ponte 60 minutos con cronómetro.
4. Corrige con esta guía y anota tus fallos: Crea un cuaderno de errores.
