Chapter 6: Analysis of Structures

6.12 Machines Machines are structures designed to transmit and modify forces. Their main purpose is to transform input forces into output forces. • Machines are usually non -rigid internally. So we use the components of the machine as a free -body. • • Given the magnitude of P, determine the magnitude of Q. Exercise 6.143 Wednesday ...
