I need some help with physics...Honestly, I'm a bit slow in the class and it's killing my GPA

How do I calculate torque and normal force?

I'm working on a lab. Basically, I'm balancing a meter stick with two different mass on both sides sides with a fulcrum in between them. I need to determine the normal force and torque.

Given:

Measured mass of meter stick: .09495 kg

Location of meter stick's center of mass: 50.5m

Trial 1:

Left of Fulcrum

mass1 [kg]: .250kg

F1:?

Length 1[m]: .150m

Torque1=Force1(Length1) [Nm]:?

Right of Fulcrum

mass2 [kg]: 100kg

F2:?

Length2 [m]: .37m

Torque2= Force2(Length 2)

Trial 2:

Left of Fulcrum...

mass1 [kg]: .300kg

F1:?

Length 1[m]: .150m

Torque1=Force2(Length2):?[Nm]

Right of Fulcrum...

mass2 [kg]: 100kg

F2:?

Length2 [m]: .445m

Torque2= Force2(Length 2):? [Nm]

Btw...is normal Force= Force of gravity in this case? and when isn't normal force equal to force of gravity?

Thank You
