what are formulas of Torque?
what does Torque have to do with Force1 + Force2 = m1g+ m2g +m3g ?

Torque is the cross product of force and a lever arm distance.
So its magnitude is force times lever arm times the sine of the angle between them or the force times the perpendicular component of the lever arm.
The equation you cited is a sum of forces. That has NOTHING to do with torques.
The sum of the forces is equal to ma (per Newton).
The sum of the torques is equal to I alpha. I is the moment of inertia, alpha is the angular acceleration.
In a statics problem, both the sum of the forces and the sum of the torques must be zero.

torque = force * prependicular distance
the prependicular distance is the shortest distance between the force line of action and the point reference to which the distance is measured
u need some distance

T = Fd
Torque = Force x Distance
