Quiz zum Vortrag
Which of the following statements is TRUE about static equilibrium?
- An object in static equilibrium has no velocity or acceleration
- An object in static equilibrium has no acceleration but can have a velocity
- An object in static equilibrium has no forces acting on it at all
- An object in static equilibrium can have a net force, but no net acceleration
- An object in static equilibrium can move side to side, but not rotate
What is the difference between translational and rotational equilibrium?
- In translational equilibrium, an object can be rotating but not translating, while in rotational equilibrium, it can be translating but not rotating about its center of mass
- In translational equilibrium, an object can be translating but not rotating, while in rotational equilibrium, it can be rotating but not translating
- In translational equilibrium, an object can be rotating or translating, while in rotational equilibrium, it cannot be translating but can be rotating
- In translational equilibrium, an object cannot be rotating or translating while in rotational equilibrium, it can be translating and rotating
- In translational equilibrium there is no net force acting on the object, but in rotational equilibrium there can be a non-zero net force acting on the object
If a force is being applied to the corner of a square, pointed directly away from the center of the square (i.e. the line of the force is parallel to the line which connects the center of the square to the corner of the square which the force is being applied), what is the lever arm of the applied torque? (Side length of square = a)
- 0
- a
- 2a
- a/2
- √2 a/2
Using the regular sign convention for angular motion, in what direction is the angular rotation of the hands of a clock?
- In the negative direction
- In the positive direction
- Positive during the first half of rotation and negative during the second half
- Negative during the first part of rotation and positive during the second half
- There is no direction for angular motion
