Answer 2

Hey dear,
This appears to be question related to manufacturing processes.

● Complete question with options is -
The coefficient of friction between the part and the tool in cold working tends to be _____ relative to its value in hot working?
(a) higher
(b)lower
(c) no different

● Answer -
(b) Lower

● Explanation -
- In cold working, lubrication is easier so friction is lesser.
- Therefore, coefficient of friction tends to be lower in cold climate.

Hope this helps you...
