At static equilibrium, the body is at rest and the forces cancel out.
An extended object is in static equilibrium if __________.
a) only the net torque acting on the object is zero.
b) either the net force acting on the object is zero or the net torque acting on the object is zero.
c) both the net force acting on the object is zero and the net torque acting on the object is zero.
d) only the net force acting on the object is zero.
Which of the following objects is in static equilibrium? Select all that apply.
Two children want to balance horizontally on a seesaw. The first child is sitting one meter to the left of the pivot point located at the center of mass of the seesaw. The second child has one-half the mass of the first child. Where should the second child sit to balance the seesaw?
a) 1m to the right of the pivot
b) 0.5m to the right of the pivot
c) 0.5m to the right of the pivot
d) 2m to the right of the pivot
