Principles Of Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






2. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

42. The reason for which something is done or for which something exists.






43. The collection and analysis of numerical data in large quantities






44. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and

46. A physical quantity that has magnitude only.






47. A switch that can provide variable motion control






48. Categorical data graph
