LECTURE 1 : STATICS - Resultant of concurrent force
We'll start with the basics. First of all, What is Statics in Civil Engineering? It is the study of effects of forces on a rigid body at rest. Above, we can see the formula for the magnitude of resultant which we'll refer to as R What is Rx and Ry? Rx is the summation of forces along the X-component and Ry is the summation of forces along Y-component. An example of forces would be presented later on. Here's a tip. What would really help you out with the computation of Rx and Ry is by mastering that basic trigonometric functions of a right triangle. We could remember this by uttering SOH-CAH-TOA. An image is provided below for further understanding of the identities. The next picture would show a presentation of slanting force and on how to compute for Rx and Ry given the Resultant force and angle. Why is it important to master this topic? The computations...
