Cam FAQs:

Q: Is a cam a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion?

A: Yes.

Q: Was a cam initially carried the weight?

A: Yes, until at the final portion of the run the profile of the non-roller cam rose more than the other causing the solid follower to take the weight.

Q: Is a cam mounted to the top of the lower sash?

A: Yes, and the follower is the hook on the upper sash.

Q: Is a cam one in which the cam element moves in a straight line rather than rotates?

A: Yes.

Q: Is a cam constant lead?

A: Yes, where the position of the follower is linear with rotation, as in a lead screw.

Q: Was a cam built into Hellenistic water-driven automata from the 3rd century BC?

A: Yes.

Q: Was a cam automatic machine tool programming cams?

A: Yes.

Q: Is a cam used in many simple electromechanical appliance controllers?

A: Yes, such as dishwashers and clothes washing machines, to actuate mechanical switches that control the various parts.

Q: Is a cam a key for a pin tumbler lock?

A: Yes.

Q: Is a cam a cam in which the follower rides on the surface of a cylinder?

A: Yes.

Q: Are cams principally used to convert rotational motion to linear motion parallel to the rotational axis of the cylinder?

A: Yes.

Q: Is a cam similar to?

A: Yes, but not identical to, that of a rotating cam.

Q: Is a cam used to provide mechanical advantage in forcing the window shut?

A: Yes, and also provides a self-locking action, like some worm gears, due to friction.

Q: Was a cam used for example in mechanical time keeping clocking-in clocks to drive the day advance mechanism at precisely midnight and consisted of a follower being raised over 24 hours by the cam in a spiral path which terminated at a sharp cut off at which the follower would drop down and activate the day advance?

A: Yes.

Q: Is a cam the cam plate which is cut out of a piece of flat metal or plate?

A: Yes.
