Torque is the rotational analogue of: Answer: Acceleration
A wooden square of side length 1 m is on a horizontal tabletop and is free to
rotate about its center axis. The square is subject to two forces and rotates. Find
the net torque of the system. Answer: 2 Nm
, A wooden square of side length 1 m is on a horizontal tabletop and is free to
rotate about its center axis. The square is subject to two forces and rotates. Where
should another 4N force be applied to maximize its rotational torque? Answer:
Bottom right corner
A wooden square of side length 1 m is on a horizontal tabletop and is free to
rotate about its center axis. The square is subject to two forces and rotates. Where
should another 4N force be applied to set the wooden square to equilibrium?
Answer: Bottom left corner
Two wheels are fixed to each other and are free to rotate about a frictionless axis
through their concentric center. As shown above, four forces are exerted tangent
to the wheels. The magnitude of the net torque is: Answer: 4FR
