Answer :
Final answer:
To prepare a square piece of wood for turning on a lathe, it should be dried, cut to size, and have its centers marked. When mounting, it is secured between the lathe's headstock and tailstock using a spur center or a chuck. The application of force from a chisel during turning does not significantly affect angular velocity.
Explanation:
The process of preparing and mounting a square piece of wood for turning on a lathe involves several steps. First, the wood should be prepared which includes ensuring the wood is dried to prevent warping, cutting the square piece to the desired size, and marking the center of the wood to aid in mounting. Second, for mounting the piece on the lathe, the center marks are used to position the wood between the headstock and tailstock. The piece is then secured using a spur center or a chuck, providing stability during the turning process.
Concerning the question about the angular velocity of a piece of wood spinning on a lathe with the application of a 50 N force by a chisel, it is not directly affected by the force applied. Instead, the chisel will remove material, potentially slightly changing the moment of inertia, and consequently, this could have a minor effect on angular velocity due to conservation of angular momentum, assuming the lathe maintains a constant rotational speed.
The concept of a square peg fitting through the square hole and a round peg fitting through the round hole is not directly related to woodturning on a lathe, as this relates more to shape sorting and recognition rather than the woodworking process.
