Question

1) A car is moving without slipping, it will have a point on its body that has zero velocity. True or False?

2) When a wheel fixed at the center, rotates and accelerate in the same direction, which of the following is generated at a point on the edge of the wheel. - Radial acceleration - Tangential acceleration - Neither radial nor tangential acceleration - Both radial and tangential acceleration

3) If a circular disk is fixed at a point located on its edge and has an angular acceleration, its mass center will only have a rotational inertia and no linear acceleration. True or False?

4) Two cylinders, A and B, of the same size and mass roll down an inclined plane without slipping. Cylinder A has most of its mass concentrated at the rim, while cylinder B has most of its mass concentrated near the center. Which Cylinder will accelerate faster?

5) A wheel of radius 1m is spinning around its center with a constant angular velocity of 2rad/s. What is the tangential component of acceleration of a point located at the rim of the wheel?

6) If a rigid body is undergoing a curvilinear translation, the linear velocity of all the points on the body will be the same. True or False?

7) Consider a cart on a horizontal frictionless surface. Once the car has been given a push and released, what will happen to the cart? - Continue with constant acceleration - Slowly come to a stop - continue with decreasing acceleration - Continue with constant velocity - Immediately come to a stop

8) Consider two identical blocks of the same mass, one resting on a flat surface, and the other resting on an incline. For which case is the normal force greater?

9) The potential energy of a rigid body depends on - Weight of the body - Height at which it's placed - Both

10) A small car collides with a large truck. Which will experience the greater impact force? - Car - Truck - Both the same - Depends on the velocity of each - Depends on the mass of each

11) Two tug of war opponent each pull with a force of 160 N on opposite ends of the rope. What is the tension on the rope?

12) A wheel is rolling without slipping and traveling to the right. In which direction the friction force will act on the wheel? - To the right - To the left

13) When an elastic spring is deflected, its potential energy will depend on the original unstretched length of the spring. True or False?

14) A plate is placed in the x-y plane and a force is applied so that it rotates about the x-axis. Which mass moment of inertia is applicable: - About the x-axis - About the y-axis - About the x-axis

15) If a rigid body is in General Plane Motion ( with translation and rotation) it's kinetic energy is influenced by its mass moment of inertia. True or False?
