For some reason I am struggling in the class. Most of my HW assignments I'm getting 90s and 100s but I haven't done well on the tests. I'm not sure if it's just my professor's grading method or if I'm just an idiot.

WebFeb 2, 2024 · In statics, moments are effects (of a force) that cause rotation. When computing equilibrium, you must be able to calculate a moment for every force on your free-body diagram. To determine a force’s moment, you use one of two different calculations, as you can see in the following list. WebThe most robust and general method to find the moment of a force is to use the vector cross product , (4.5.1) (4.5.1) M = r × F, 🔗 where F is the force creating the moment, and r is …
WebThere are three equilibrium equations for force, where the sum of the components in the x, y, and z direction must be equal to zero. The body may also have moments about each of the three axes. The second set of three equilibrium equations states that the sum of the moment components about the x, y, and z axes must also be equal to zero. We ... WebIn mechanics, a couple is a system of forces with a resultant (a.k.a. net or sum) moment of force but no resultant force. [1] A better term is force couple or pure moment. Its effect is to impart angular momentum but no linear momentum. In rigid body dynamics, force couples are free vectors, meaning their effects on a body are independent of ...
