Hi, i have a shaft with OD = 33.40mm Wall Thickness = 3.38 mm length = 2.4m
Density of shaft = 2750
The weight per unit length that is given is 0.8555 kg/m
My question is how did they get it as I am using the volume formula for a cylinder which is
V=Pie*h(R^2 - r^2) then i times this by the density 2750 to get the mass but i get
1.111 which then divided by 2.4 would be 0.463.
Where am i going wrong.
Thanks for any help
