Lesson Objective: In this lesson, we will learn about defining Force and Torque.
USAGE OF FORCE AND TORQUE
With the Force/Torque tool in mechanism, you can introduce external forces or torques into your model that are not due to impact or forces caused by servo/force motors.
When you apply a force/torque, you have three different options:
· Point Force – The force is applied to a datum point on a body, at a specified magnitude and direction.
· Body Torque – The torque is applied at the center of mass on a specified body. The magnitude and direction of torque is then specified.
· Point to Point Force – The force is applied equally and opposite two selected points. If the two points are coincident, the value is zero.
For the magnitude of the force/torque, you have additional options for how you specify it:
· Constant – A constant force is applied to the object.
· Table – Use a table to define force as a function of time.
· User Defined – Create your own function to define the force using an equation editor.
· Custom Load – Write special programs to define your forces. This is not standard out-of-the-box functionality, and will not be covered in this course.
