AI Thread Summary
To determine the required wing area for a 2000lb plane landing at 35mph with a maximum lift coefficient (CL) of 1.50, the lift formula is applied: lb = CL * ρ * A * v^2 / 2. In this equation, ρ represents the air density at the landing strip, which is crucial for accurate calculations. The setup leads to the equation 2000 = 1.50 * ρ * A * (35)^2 / 2, from which the wing area (A) can be solved. It's important to ensure that all units are consistent to avoid errors in the calculation. Understanding these parameters is essential for determining the appropriate wing area for safe landings.

What wing area should a plane weighing 2000lbs have to enable it to land at a speed of 35mph?
Max CL= 1.50


Formula for lift

lb= CL*ρ*A*v^2/2

when i set up the problem i get this

2000= 1.50*ρ*A*(35)^2/2 and i realize I am trying to solve for A (area) but what does the ρ stand for? I read its stands for the density of the fluid

The rho is density of air at the landing strip. Watch your units!
