Types of loading

In mechanical terminology, the term load indicates that external force/weight, either constant or variable, acts on a mechanical member/structure. The weight of an object of a specific material is also an external load, and the external force that works on a structure comes under the categories of loading. The external load generates its effects as stress and strain in the structure.

Problem 3: Now we will repeat the previous problem using the Cartesian method. Values: FA = 20 N FB = 30 N a = 25° Use the Cartesian method to determine... a) the magnitude of the resultant force on the bolt. b) the angle made by the resultant, as measured relative to the positive x-axis. Break individual forces into Cartesian components This is the method you are probably more familiar with. We are going to break each force into its respective x and y components, and then add the components together to get the resultant. We can therefore check our answers to the previous problem. Add components along x & y FA This is what we do in the real world by the way. When we don't have answers in the back of the book, we use different methods of achieving the same result, and if we don't get the same result, we know something is wrong. Here's an illustration of what we're doing: FIX X α FRY FB FRX Determine magnitude and direction of resultant
