What is the torque τB about axis B due to the force F⃗ ? (B is the point at Cartesian coordinates (0,b), located a distance b from the origin along the y axis.)
Express the torque about axis B in terms of F, θ, ϕ, π, and/or other given coordinate data.
τ = RF sin (θ)
The Attempt at a Solution
So I know that the answer is Tb = bFsin (pi/2+θ)
What I don't understand is how to get pi/2+θ?
I know that θ is the angle between r vector and F vector and since that's the case shouldn't the answer be pi/2-θ?
