what is the resultant force with which the support pushed upward on the meter stick

[Aakanksha]

Consider perfect meter stick with four masses hanging from it. The stick is on a support stand at .45 meters from the end. The meter stick has a mass of .089kg and is in a state of equilibrium, translational and rotational. There are 4 masses hanging from the tick with masses and positions. M1= .04kg at .04 m mark

M2= .2kg at the .3 m mark

M3= .25kg at the .73 m mark

M4= .1kg at the ??? mark

a) what is the equation of the rotational equilibrium?

b) what is the position of M4

c) which masses causes tccw and tcw(torques counter clockwise and torques clockwise)? Assume 0.0 end of meter stick is to the left

d) what is the resultant force with which the support pushed upward on the meter stick?
