In this drill example, a table shows the potential value for each force, including the force pulling down on the weight of the drill (gravity), the force of the user pushing in the material being drilled, the force of the trigger being pulled, and the torque of the motor trying to rotate the drill and drill bit.
It utilizes the intrinsic muscles of the hand, which are four muscle groups that work together to provide dexterity and fine motor control to the fingers and thumb. 5.
By providing quantitative data and information, the software helped to avoid rounds of physical testing (requiring physical prototypes, pneumatic motors and accelerometers) that would have affected the project’s timeline and cost.
