Question

Identify the wood turning equipment and what it does.

A _________ is used to turn wood. It rotates and carves wood to produce a ____________ form.
O highly polished
O perfectly symmetrical
O roughly finished
O Lathe

Answer 1

A lathe is used to turn wood and create perfectly symmetrical forms. The angular velocity of the piece could potentially decrease due to the force of the chisel applied. So, option D is correct.

Step-by-step explanation:

The wood-turning equipment used to turn wood is called a lathe. It mechanically rotates the wood around a horizontal axis and allows a carver to shape the wood using a chisel or other cutting tools. When carving on a lathe, the aim is to create perfectly symmetrical objects, which can range from simple cylindrical shapes to more complex forms like table legs, bowls, or decorative ornaments.

Regarding the change in angular velocity when a chisel is applied to a spinning piece of wood on the lathe, the force exerted by the chisel can affect the speed of the rotation, depending on the torque generated and the moment of inertia of the wood-and-lathe system. The angular velocity does not increase by 0.1 Nom multiplied by the moment of inertia of the wood. Instead, option b is closer to reflecting the impact of added torque which might cause a decrease in angular velocity due to the chisel force impacting the system; it's more nuanced, involving calculations of angular momentum and conservation laws.
