Kinematics and Dynamics Final Exam

Some of the in class questions and concepts focusing on Ch 7-11

Centripetal means:

Acceleration is toward the center of the radius

Acceleration is

The rate of change of the velocity with respect to time. Can be linear or angular.

Centrifugal means:

Apparent force acting on a body from the center outward due to the body’s inertia

Tangential accelerarion

Perpendicular to the radius

Absolute acceleration

With respect to the global coordinate axis

Relative acceleration

With respect to each other (e.g., two points on different bodies)

Gaspard-Gustave de Coriolis

French Mathematician, mechanical engineer, and scientist. One of the 72 scientist whose name is inscribed on the Eiffel tower

Coriolis Effect

Caused by the earth’s rotation, objects deflect to the right in the northern hemisphere.

What do you need to calculate the linear acceleration of any point on a linkage?

Instant center and Angular acceleration of linkage with respect to IC

Human tolerance of Acceleration and Velocity

Humans cannot actually feel velocity, but humans can feel acceleration
