What is the disadvantage of friction in engineering mechanics?
32. What is the disadvantage of friction in engineering mechanics?
- It enhances the stability of objects on inclined planes
- It generates heat, leading to energy loss
- It facilitates the gripping of tires on roads
- It aids in the tightening of screws and bolts
Answer
The correct answer is: B) It generates heat, leading to energy loss
Explanation
Friction generates heat as a result of the resistance between two surfaces, leading to energy loss which can be undesirable in certain mechanical systems.
