Would base isolators be able to protect a building if the ground moves up and down?
Would base isolators be able to protect a building if the ground moves up and down? It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus protecting a building or non-building structure’s integrity. Contrary to popular belief base isolation […]
Are multiple choice tests accurate?

What is the Bergeron process in simple terms?
What is the Bergeron process in simple terms? The process by which precipitation is initiated in a mixed cloud with a temperature below freezing. Because the equilibrium vapour pressure of water vapour with respect to ice is less than that with respect to liquid water, ice crystals grow at the expense of supercooled water droplets. […]
