Enter the mass (kg), the acceleration due to gravity (m/s^2), and the radius (m) into the calculator to determine the Gravitational Torque. 

Gravitational Torque Formula

The following formula is used to calculate the Gravitational Torque.

Tgravity = m*g*r

  • Where Tgravity is the Gravitational Torque (N-m)
  • m is the mass (kg) 
  • g is the acceleration due to gravity (m/s^2) 
  • r is the radius (m) 

How to Calculate Gravitational Torque?

The following example problems outline how to calculate the Gravitational Torque.

Example Problem #1

  1. First, determine the mass (kg). In this example, the mass (kg) is given as 13 .
  2. Next, determine the acceleration due to gravity (m/s^2). For this problem, the acceleration due to gravity (m/s^2) is given as  9.81 .
  3. Next, determine the radius (m). In this case, the radius (m) is found to be 90.
  4. Finally, calculate the Gravitational Torque using the formula above: 

Tgravity = m*g*r

Inserting the values from above and solving yields: 

Tgravity = 13*9.81*90 = 11477.7 (N-m)


Example Problem #2

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

mass (kg) = 14

acceleration due to gravity (m/s^2) = 9.81

radius (m) = 40

Enter these given values yields: 

Tgravity = 14*9.81*40 = 549.36 (N-m)
