Modify Force

Right-click single-component force → Modify

Modifies the following for a Single-component force:

■Force direction, if only one part is affected.

■Action body to which the force is applied. If you created the force between two parts, you can also change the reaction body. You cannot change a force created on one part and ground to a force created between two parts because the direction methods are not compatible. You’ll have to delete the force and create it again.

■Force magnitude.

■Force graphics

The options available in the dialog box change depending on the direction of the force.

■How To create a single-component force:

■Specifying Force Direction for Single-Component Forces

■Modifying Single-Component Forces

For the option:	Do the following:
Name	Displays the name of the force.
Direction	Set the number of parts affected and the direction of the force: ■On One Body, Fixed in Space - Sets the force direction so it is applied to a part. The force direction is fixed on ground. ■On One Body, Moving with Body - Sets the force so it is applied to a part. The part defines the direction of the force. ■On One Body, Moving with Other Body - Sets the force so it is applied to a part. A second part (the direction part) defines the direction of the force. ■Between Two Bodies - Creates a force between two parts. One of the parts can be ground. You cannot change a force on one part to a force defined between two parts or the reverse. You can, however, change a torque on one part to a torque on two parts or the reverse.
The following text boxes are available depending on how you defined the direction of the force.
Body	Change the action body to which the force is applied.
Action Body	For a force defined between two parts, change the action body to which the force is applied.
Reaction Body	Change the body that receives the reaction forces.
Direction Body	Change the body that defines the direction of the force if you selected the direction option, On One Body, Moving with Other Body.
Define Using	Enter how you want to define the force. Select: ■Function to define using a numerical value or function expression. ■Subroutine to define using a user-written subroutine SFOSUB.
Function	If you selected Function for Define Using, enter the following in the Function (time) text box that appears: ■Constant force value ■Function expression To enter a function expression, next to the Function text box, select the More button to display the Function Builder.
Parameters and ID	If you selected Subroutine for Define Using, enter the parameters to be passed to a user-written subroutine and its ID. Entering an ID is optional.
Routine	Specify an alternative library and name for the user subroutine SFOSUB. Learn about specifying routines with ROUTINE Argument.
Force Display	Set whether you want to display force graphics for one of the parts, both, or none. By default, Adams View displays the force graphic on the action body for single-component forces.
