Forces on a screw

WebA screw jack is a mechanical device that can increase the magnitude of an effort force. The effort force for a screw jack when neglecting friction can be expressed as F = (Q p) / (2 π R) (1) where F = effort force at the end of the arm or handle (lb, N) Q = weight or load (lb, N) p = pitch - distance or lead of thread in one turn (in, m) WebA screw is defined by a six dimensional vector of forces and torques. It can represent any spatial movement of a rigid body (as written here). But I don't get the following distinction between screw and wrench: The force and torque vectors that arise in applying Newton's laws to a rigid body can be assembled into a screw called a wrench.

WebThe screw jack consists of two simple machines in series; the long operating handle serves as a lever whose output force turns the screw. So the mechanical advantage is increased by a longer handle as well as a finer screw thread. However, most screw jacks have large amounts of friction which increase the input force necessary, so the actual ... WebScrew theory is the algebraic calculation of pairs of vectors, such as forces and moments or angular and linear velocity, that arise in the kinematics and dynamics of rigid bodies.
