Winds provide the energy to set the 1940 Tacoma Narrows Bridge motion Oscillations travel to the central span and reflected from support towers. By the principle of superposition the primary and reflected waves turn into a standing torsional wave
Temperature: measure of the motion of the individual atoms and molecules in a gas liquid or solid related to average kinetic energy of constituents High temperature: constituents are moving around energetically
At ordinary temperature, matter exists in one of three states Solid- has a shape and forms a surface Liquid- has no shape but forms a surface Gas-has no shape and forms no surface What do we mean by“ fluids”? F| uids are“ substances that flow
