Já reparou naquela fumaça branca que os aviões deixam no céu? 🌍✈️ Ela não é poluição, nem produto químico — é apenas vapor de água que congela a grandes altitudes, formando os famosos contrails. Descubra como funciona esse fenômeno incrível da aviação! #curiosidades #engenharia #avião #física

A função martelete em uma furadeira permite perfurar superfícies mais duras, como concreto e alvenaria, através de impactos rápidos e repetitivos na broca. Esse modo de percussão facilita a penetração em materiais resistentes, mas deve ser usado com cuidado para não danificar superfícies mais frágeis, como madeira e metal. #engenharia #curiosidades #Maquinas
