There is evidence that liquid water existed on Mars at some time in the past. What is the evidence found indicating the presence
Norma-Jean [14]
There mag be water on Mars but it’s not very easy to spot, but that is besides the point,

amm1812

Answer:

X_cp = c/2

Explanation:

We are given;

Chord = c

Angle of attack = α

p u (s) = c 1

​p1(s)=c2,

and c2 > c1

First of all, we need to find the resultant normal force on the plate and the total moment about leading edge.

I've attached the solution
