Question

1. Based on the image below, identify which aerodynamic force on the airplane matches each arrow(a-d). a. Arrow A- b. Arrow B- c. Arrow C- d. Arrow D- ​

Answer 1

Based on the image, the arrows represent different aerodynamic forces acting on the airplane. Let's match each arrow with the corresponding force:

a. Arrow A: Lift - Arrow A represents the lift force. Lift is the force that acts perpendicular to the direction of motion and supports the airplane in the air. It opposes the force of gravity and allows the airplane to stay aloft.

b. Arrow B: Thrust - Arrow B represents the thrust force. Thrust is the force that propels the airplane forward. It is generated by the engines and counteracts the drag force.

c. Arrow C: Drag - Arrow C represents the drag force. Drag is the force that opposes the motion of the airplane through the air. It is caused by air resistance and acts in the direction opposite to the motion of the airplane.

d. Arrow D: Weight - Arrow D represents the weight force. Weight is the force exerted by gravity on the airplane. It acts vertically downwards and is equal to the mass of the airplane multiplied by the acceleration due to gravity.

To summarize:

- Arrow A represents lift, which supports the airplane in the air.

- Arrow B represents thrust, which propels the airplane forward.

- Arrow C represents drag, which opposes the motion of the airplane.

- Arrow D represents weight, which is the force exerted by gravity on the airplane.

Understanding these forces is essential in understanding the aerodynamics of an airplane and how it is able to fly.

Answer 2

Identifying aerodynamic forces on an airplane usually involves lift, weight, thrust, and drag. Without the specific image, it's not possible to determine which arrow corresponds to each force. A free-body diagram helps illustrate these forces in relation to the airplane's orientation.

Step-by-step explanation:

The question appears to be related to physics, more precisely to the topic of aerodynamics and force diagrams. Without the specific image, it's not possible to provide the exact answers to which aerodynamic force corresponds with each arrow (A-D). However, aerodynamic forces that act on an airplane typically include the following:

Lift - This force acts perpendicular to the oncoming flow direction. It is generated by the dynamic effect of the air acting on the wing and opposes gravity.

Weight - This is the force due to gravity pulling the airplane towards the Earth and acts downwards.

Thrust - This is the force produced by the engines to propel the aircraft forward and acts in the direction of motion.

Drag - This force acts opposite to the direction of motion and is caused by friction and differences in air pressure.

When performing these identifications, a free-body diagram would be useful where lift is usually represented by an arrow pointing upward, weight by an arrow pointing downward, thrust by an arrow in the direction of the motion, and drag by an arrow in the opposite direction of motion.
