Problem $3)$ The horizontal $20$ N force $($in the $x-y$ plane$)$ acts on the handle at point $A.$ In other words, that $60$ is measured counterclockwise from theypositive $y-$axis. Answer the following questions and report your answers as vectors.

a$)$ What is the moment generated by the force about point $O?(10$ pts$)$

b$)$ What is the moment generated by the force about point $B?(10$ pts$)$

c$)$ What is the moment about the axis $OB$ from the force? $(5$ pts$)$
