Concept explainers

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

Adjustable Link L m Pivot Pivot Screw 'B' Gripper In the drawing, arm A is being driven back and forth in the direction of the arrows. It is connected to a gripper by way of an adjustable link L, two horizontal bars and two vertical bars. Screw B is a shoulder screw secured to arm A, but allows the horizontal bar to pivot around it. If the shoulder screw B was lowered towards the end of arm A, and the stroke of arm A remained the same, the stroke of the gripper would: Arm 'A' 0 MIMINIA
