For momentom:
M= 4*4cos(30)-2*4sin(30)
(clockwise)-(anticlockwise)
=9.856(clockwise).
M= 4*4cos(30)-2*4sin(30)
(clockwise)-(anticlockwise)
=9.856(clockwise).

That is simple by taking moment in x & y for x the perpendicular distance is 2 & for y is 4.
mx=fsin30 & my=fcos30.
m=fsin30 2 + fcos30 4.
mx=fsin30 & my=fcos30.
m=fsin30 2 + fcos30 4.
