Solving Frame Problems Statics Webframes Org Frames are rigid, stationary structures designed to support loads and must include at least one multi force member. đź”—. machines are non rigid structures where the parts can move relative to one another. generally, they have an input and an output force and are designed to produce a mechanical advantage. 6.7 summary. 6.7. summary. đź”—. the various equilibrium topics we have covered and the associated problem solving techniques are summarized below. đź”—. you should be able to recognize these situations, draw the associated free body diagrams and solve for the unknowns of each case. đź”—.
Solving Frame Problems Statics Webframes Org A frame or a machine is an engineering structure that that contains at least one member that is not a two force member. figure 5.6.1 5.6. 1: this horizontal beam is connected to other members (where normal forces would exist) at more than two locations. this beam is therefore not a two force member. In this book, we will label everything by assigning letters to each of the joints. figure 5.7.1 5.7. 1: the first step in the analysis of frames and machines is to label the members. next you will need to determine if we can analyze the entire structure as a rigid body. in order to do this, the structure needs to be independently rigid. Figure 6.6.2. machines contain multi force members that can move relative to one another. analyzing frames and machines involves disassembling the structure into individual rigid bodies; we “take the structure apart” and analyze each part separately. each component is analyzed as an independent rigid body. Frames and machines example 4 given: the frame shown is loaded with a 100kg package and is supported by pin supports at joints a and b. the frame is in static equilibrium. find: a) identify any two force members in the frame. b) draw the overall free body diagram and the individual free body diagrams of members ace and bcd, and pulley e.

Statics can be applied to a variety of situations, ranging from raising a drawbridge to bad posture and back strain. we begin with a discussion of problem solving strategies specifically used for statics. since statics is a special case of newton’s laws, both the general problem solving strategies and the special strategies for newton’s.
