Homework Statement
Find the torque at point (1,5,2), first with respect to the origin and then with respect to the y-axis.
F=2i-3j+k
Homework Equations
T=r x F
The Attempt at a Solution
Torigin= 11i+3j-13k ; Tyaxis=6i+3j-3k here I defined a new vector r'=1i+2k
What I don't understand is what exactly "torque with respect to y axis" means. Does it mean I have a gigantic cylinder, laying around my axis and can only rotate in that direction? What does it mean? How does one interpret the fact that you can have multiple torques if you define new references?
Thanks. Sorry if this question is dumb.[/B]
