Question

explain the experimental procedure to under stand nature of the friction and concept of static friction​

Answer 1

Answer:

An experimental study is conducted to measure the static friction which is the coefficient under constant normal load and different interface conditions. These are including surface roughness, dwell time, displacement of the rate, as well as the presence of the traces of lubricant and wear debris at the interface.
