$M_O=36.7N*m \circlearrowleft$

Work Step by Step

We will sum the torques about point O $(+ \circlearrowleft) \sum \tau_O$ $-(\cos(30^{\circ}))F*(\sin(45^{\circ}.3m)+(\sin(30^{\circ})F*(0.4m+\cos(45^{\circ}).3m)$ $-(\cos(30^{\circ}))(300N)*(\sin(45^{\circ}.3m)+(\sin(30^{\circ})(300N)*(0.4m+\sin(45^{\circ}).3m)$ $+36.7N*m$ $36.7N*m \circlearrowleft$
