True/False statics and dynamics

In plane rotation, a body rotates about AN AXIS THAT IS PARALLEL TO THE PLANE OF MOTION

false

In rotation, the normal component of acceleration at the body's center of mass G is always DIRECTED FROM THE CENTER OF ROTATION TOWARD G

false

A body subjected to general plane motion undergoes BOTH THE RECTILINEAR AND CURVILINEAR TRANSLATION

false

If a disk rolls on a rough surface without slipping, the friction force between the body and the surface needs to be GREATER THAT USN

false

If a rigid body is rotating with a constant angular velocity about a fixed axis, the velocity at a point P that is r distance away from the rotating center is the ANGULAR VELOCITY TIMES THE SQUARE OF THE DISTANCE

false

If a rigid body undergoes a translation only, the difference in velocity at points A and B on the rigid body IS ALWAYS DEPENDENT ON THEIR POSITION

false

Kinetic energy due to rotation of a rigid body is defines as THE MOMENT OF INERTIA ABOUT THE MASS CENTER TIMES THE ANGULAR ACCELERATION

false

The elastic potential energy stored in an elastic spring is typically NEGATIVE

false

The internal impulses acting on a system of particles in a rigid body ALWAYS EQUALS THE EXTERNAL IMPULSES

false

The kinetic energy of a rigid body consists of the kinetic energy due to THE DEFORMATION OF THE BODY

false

The linear impulse and momentum equation is obtained by integrating the EQUATION OF MOTION WITH RESPECT TO DISPLACEMENT

false

The principle of linear impulse and momentum describes the RELATIONSHIP AMONG FORCE, VELOCITY, AND DISPLACEMENT of a motion

false

The ratio of the restitution impulse to the deformation impulse is called COEFFICIENT OF DEFORMATION

false

The rotational EoM about the mass center indicates that the sum of moments due to the external loads equals TO THE MOMENT OF INERTIA TIMES THE TANGENTIAL ACCELERATION.

false

When a motion of one or both of two particles is at an angle to the line of impact, THE IMPACT IS SAID TO BE A MINOR IMPACT

false

When a rigid body experiences general plane motion, the sum of the moments of all external forces about any point P is equal to Ip(alpha)+map

false

When a rigid body rotates about point O, the kinetic moment of the body about point O equals THE MASS TIMES THE ACCELERATION AT O

false

When a rigid body undergoes a general plane motion, the net work done by the internal forces is zero, SINCE THE INTERNAL FORCES ARE RELATIVELY SMALL COMPARED TO THE EXTERNAL FORCES

false

When a rigid undergoes translational motion due to external forces, the translational equations of motion can be expressed for ANY ARBITRARY POINTS

false
