This quiz delves into fundamental concepts of physics related to pressure, buoyancy, and aerodynamics. It includes questions about the manipulation of pressure in a rectangular box, calculating the pressure exerted by a solid cylinder, and understanding buoyant forces on floating bodies. Further, it explores hydraulic systems, Bernoulli’s principle in relation to airflow, and the functionality of ailerons in causing airplane tilt during flight. Perfect for reinforcing key physics concepts!
E N D
1 • A rectangular shoe box is on a table with the largest side down. It is manipulated to place the smallest side down. Has the pressure on the table changed? Why?
2 • A 75 Kg solid cylinder that is 2.5 m long and has an end radius of 7.0 cm stands on one end. How much pressure does it exert?
3 • What is the buoyant force acting on a 100 Kg body floating in water?
4 • In using a hydraulic system, what is the “Trade-Off” for multiplying the force?
5 • Fa = 100 N • Fb = ? • Areaa = 10 cm2 • Areab = 300 cm2 • Find Fb
6 • According to Bernoulli, what happens to air as it speeds up? How does that help an airplane fly?
7. • Why do ailerons cause an airplane to “Tilt” as it is flying?
