Exercise 5: What is the efficiency of a machine that has work inputof 40 joules and work output of 35 joules? Exercise 6: Work output of a large machine in a factory is 89,000 joules, and its input is 102,000 joules. Pearson Education, Inc., publishing as Pearson Prentice Hall. All rights reserved.
