A nut is fixed to a given mass. A screw is in the nut. What is the formula to calculate the torque required to lift the mass (the screw is attached to a frame, and the mass cannot turn on its axis)?

The general equation for torque is given as:
Torque = r F sin theta
Where:
r = the vector from the axis of rotation to the point on which the force is acting.
F = force vector
theta = angle between r and F
Beyond that I can't really help you without more information.

depends if the nut is rusty,if it is stainless,etc..
for all will not be the same some will constricted so tight it will require ,more energy to break it loose
