A rigid bar that is supported at one point
A rigid bar that is supported at one point is a physical object that is capable of maintaining its shape and integrity. It is supported by a fixed point or pivot, allowing it to rotate or move freely around that point. This support can be achieved through various mechanisms such as a hinge, pin, or ball joint.
One common example of a rigid bar supported at one point is a seesaw or teeter-totter. In this case, the bar is fixed at its center point, allowing it to rotate up and down. The weight or force applied on either end of the bar causes it to tilt and balance.
Another example is a simple lever, where a rigid bar is supported by a fulcrum. This setup is used in various applications, from basic-level tools like scissors to more complex systems like crowbars or even see-saw mechanisms used in heavy machinery.
The support at one point allows the bar to rotate or move, but it does not allow for any deformation or bending of the bar itself. This rigidity ensures that the bar remains stable and maintains its shape under the applied forces or loads.
