The magnitude of the torque is
Explanation:
The torque exerted by a force acting perpendicular to the arm is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the pivot
In this problem, the force acting on the gymnast is his weight, so the magnitude is given by
where
m = 68 kg is the mass of the gymnast
is the acceleration of gravity
Now we can use the first equation to find the torque, where
d = 2.2 m
And substituting,
