What is a screw thread?
Q: What is a screw thread?
A: A screw thread is a helical structure wrapped around a cylinder or cone that gives mechanical advantage.
Q: What are the two types of screw threads?
A: The two types of screw threads are straight threads and tapered threads.
Q: How does tightening a nut to a bolt work?
A: Tightening a nut to a bolt is like driving a wedge into a gap until it sticks through friction and plastic deformation.
Q: What is the mechanical advantage of a screw thread dependent on?
A: The mechanical advantage of a screw thread depends on its lead, which is the linear distance the screw travels in one turn or revolution.
Q: How many simple machines give mechanical advantage?
A: Six simple machines give mechanical advantage, and a screw thread is one of them.
Q: What is a straight thread?
A: A straight thread is a screw thread wrapped around a cylinder in the form of a helix.
Q: What is a tapered thread?
A: A tapered thread is a screw thread wrapped around a cone in the form of a helix.
