A blimp is moored to a tower at .A from this blimp is
F = 5i + 3j + 1.8k kn
what is the moment about Axis C on the ground?
knowledge of this moment and other moment at the base is needed to properly design the foundation of the tower.
Hight of tower = 50m
angle = 45°

Explanation:
Force applied over a particle, F=(5i+3j+2k)\ NF=(5i+3j+2k) N
Displacement from its origin, r=(2i-j)\ Nr=(2i−j) N
We know that the dot product of the force and displacement is equal to the amount of work done. Mathematically, it is given by :
W=F.rW=F.r
W=(5i+3j+2k).(2i-j)W=(5i+3j+2k).(2i−j)
We know that, i.i = j.j = k.k = 1
W = 7 joules
So, the work done on the particle is 7 joules. Hence, this is the required solution.
