A pin is 20 cm away from the left edge of the meter stick.
An unknown mass, m1, is placed a distance 5cm from the leftedge.
m2 = 12 kg placed 40 cm from the left edge.
The meter stick that the masses hang on, m(stick) = 1kg
A center of gravity is located 50cm from the left edge.

External force F1= 15 N at 30 degrees, 1 meter away from theleft edge.
What are the quantities of torques of: M2, center of gravity,and clockwise component.
Then find torque of external force.
Finally, find the mass of M1.
Thank you so much, in advance. This is really confusingme..
