Question

an airplane has a tendency to descend in a turn because _____. (5.c.1) 1 point thrust is not equal to drag. the vertical component of lift decreases. the airplane is in a skid. the horizontal component of lift decreases. a person weighing 180 pounds and experiencing 4 gs of force would feel as though they weighed _____. (5.c.2) 1 point 45 pounds. 360 pounds. 540 pounds. 720 pounds.

Explanation:

First Question (Airplane Turn Descent)

To determine why an airplane descends in a turn, we analyze lift components. In a turn, lift is split into vertical (supports weight) and horizontal (causes turn) components. When turning, the vertical component of lift decreases (since total lift is angled), reducing the upward force to balance weight, leading to descent. Other options: Thrust - drag imbalance relates to speed, not descent in turn; a skid is an improper turn, not the cause of descent; horizontal component increase (not decrease) causes turning.

Step1: Recall G - force effect on weight

G - force multiplies apparent weight. The formula is $Apparent\ Weight = Actual\ Weight\times G - force$.

Step2: Substitute values

Given actual weight = 180 pounds, G - force = 4. So, $Apparent\ Weight = 180\times4 = 720$ pounds.

Answer:

B. The vertical component of lift decreases.
