net torque with theta included?

Question

calculate net torque on a beam about a following axes
both counterclockwise
O: at 45degrees and 35 N
C: at 30 degrees and 25N
both at r= 2.0 m

Answer 1

In general

T=r x F or

T= r F sin(A) A- angle between the beam

O: T= 2.0 x 35.0 x sin(45) = 49.5= 50.0 m N
C: T= 2.0 x 25.0 x sin(30) = 25.0 m N
