Calculate the tension in a rope supporting a mass in an Atwood machine configuration with two hanging masses. The tension depends on both masses and gravitational acceleration.
Enter your values below
First hanging mass
Second hanging mass
Default is 9.81 m/s²
How this calculator works
Tension equals two times the product of the masses times gravitational acceleration, divided by the sum of the masses.
