What wind velocity is required to topple an empty tractor trailer, as shown here? The trailer is 48 ft long, 8 ft wide, 12 ft tall, and the trailer floor is 4 ft above the road surface, giving the trailer a square cross section. It weighs 13,500 lb. Assume the air p= 0.0023 slug/ft³ and kinematic viscosity v = 1.5 x10+ ft²/s.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
