CIE 525 Lecture Notes - Lecture 10: Cross Product, Vector Analysis, Net Force
Document Summary
Find an equivalent force-couple system for a system of. Determine moments for a force in 2-d and 3-d cases. Determine equivalent force for a distributed load system. Applications: wrench on the pipe, what is the effect of the. The moment of a force about a point provides a measure of the tendency for rotation. In the 2-d case, the magnitude of the moment is. Mo is either clockwise or counterclockwise depending on the tendency for rotation. Often it is easier to determine mo by using the components of f. Given: a 400 n force is applied to the frame and q = 20 . Find: the moment of the force at a. Given: a 40 n force is applied to the wrench. Find: the moment of the force at o. Moments in 3-d can be calculated using scalar (2-d) approach but it can be difficult and time consuming.
