5 Questions
Explain the purpose of flywheel in machines and mechanisms.
The flywheel is used to store rotational energy and smooth out the power output from a machine or to maintain constant speed.
Explain the purpose of cams in machines and mechanisms.
Cams are used to convert rotary motion into linear motion or vice versa, and are often used in mechanisms to control the timing of valve opening and closing in engines.
Describe the role of brakes and dynamometers in machines and mechanisms.
Brakes are used to stop or slow down the motion of a machine, while dynamometers are used to measure the power output of a machine.
What are governors and what is their function in machines?
Governors are devices used to control the speed of a machine, and they work by regulating the flow of fuel or working fluid to the machine.
What is the function of ball and roller bearings in machines?
Ball and roller bearings are used to reduce friction and provide smooth rotation between two moving parts in a machine.
Test your knowledge of the theory of machines, which deals with the study of relative motion between various elements of a machine and the forces acting on them. Explore concepts related to mechanical systems and their behaviors.
