Is there a direct or indirect relationship between force and mass?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
