Im trying to work out the stress of a fishing line after connecting a fishing line to a pulleyboard and adding 100g weights one at a time onto the fishing line to create strain and stress.
I know the formula is Stress = Force divided by area
And i have already worked out the force acting on the fishing line for each 100 gram weights which are added. If i have done this right it is 0.1 (100 g) multiplied by 9.81 (gravity) to give 0.981.
Also i have the diameter of the fishing line as 35 microns (3.5 x 10 to the power of -5)
So the area of the cross section of the circular fishing line is needed and then needs to be multiplied by the length of the fishing line which is 1.2 metres.
Can anyone help me out with this please?
Thank you so much
Stress = Force / Area
Area of circular fishing line = pie x radius squared x length of fishing line (1.2 metres)
