This force is called lift. In heavier-than-air craft‚ lift is created by the flow of air over an airfoil. The shape of an airfoil causes air to flow faster on top than on bottom. The fast flowing air decreases the surrounding air pressure. Because the air pressure is greater below the airfoil than above‚ a resulting lift force is created. To further understand how an airfoil creates lift‚ it is necessary to use two important equations of physical

While she was doing that I was screaming and calling my dad.

What is the relationship of lift‚ drag‚ thrust‚ and weight when the airplane is in straight-and-level flight? Lift equals weight and thrust equals drag. During the transition from straight-and-level flight to a climb‚ the angle of attack is increased and lift is momentarily increased. During a steady climb‚ the angle of climb depends on excess thrust. A propeller rotating clockwise‚ as seen from the rear‚ creates a spiraling slipstream that tends to rotate the aircraft to

So you lift more‚ strain your muscles more and you overwork yourself. The consequence? Torn muscles and tendons and diminished self esteem. Thus‚ it is important to follow safety in weightlifting to avoid such things from happening. The concept of weight lifting is simply to increase muscle activities and speed

Solve each of the following problems. Show your solution. 1. A hydraulic lift office chair has its seat attached to a piston with an area of 11.2 cm2. The chair is raised by exerting force on another piston‚ with an area of 4.12 cm2. If a person sitting on the chair exerts a downward force of 219 N‚ what force needs to be exerted on the small piston to lift the seat? Answer: a= 11.2 cm2 A= 4.12 cm2 f= 219 N F= 80.56 N F= fA / a ;
