Una varilla uniforme de 255 N y 2.00 m de longitud carga un peso de 225 N en su
extremo derecho, y un peso desconocido W hacia su extremo izquierdo (figura). Cuando
W se coloca a 50.0 cm del extremo izquierdo de la varilla, el sistema se equilibra
horizontalmente cuando el pivote está a 75.0 cm del extremo derecho. a) Calcule W. b)
Si W se mueve ahora 25.0 cm a la derecha, ¿a qué distancia y en qué dirección debe
moverse el pivote para restablecer el equilibrio?
