Homework Statement
Hello friend, i really stuck on how to calculate this thing. I have to find the drag force and lift force acting on fishing lure. By the way, the fishing lure has lip and there an angle on the lip.I am sorry my english is bad but i hope you can understand what i am trying...
thanks for your explanation, okay, in this fishing lure, the lure will retrieve so that the lure will going down to dive..so the lift force will indivate negative sign as show the lure is going down...this is my opinion.
For F=m(g-a)---->a is measured vertically or horizontally??
However...
hello buddy, sorry for late reply, still doing revision on this..i forgot to mention that the lure has angle = 14 degree...so it should be
x component
F cos 14 = Drag
then m(g-a)cos 14 = drag am i right??
but for lift, since calculation on x component has cos 14 so for y component
F sin 14...
I mean in Ansys, i just used all the surface area as wetted area and not cross-section. The lure is also have lip on front of mouth portion..but honestly i also confusing about the Area that i must use. can you correct me if i am wrong??
I tried to use this formula
acceleration taken from experimental, a = 0.03 ms^2
So, F=ma=Drag
m(a + g)= Drag
(0.01874 kg)(0.03 ms^2 + 9.81 ms^2) = 0.8035 N
Lift Force
Lift=W - Fb
Where Fb is (spesific weight)(volume of fishing lure)
= (0.01874kg)(9.81) -...

Hello guys, I am here and really need your help.
In the figure below, the water flow from inlet and then out at outlet with velocity, v = 0.71 m/s. The objective is to calculate find the drag force and lift force act on fishing lure. I have done Ansys Fluent analysis but...
