Question
Chapter 9, Problem 79QAP
Interpretation Introduction
Interpretation:
The pressure exerted on the skate blade and also the decrease in melting point at this pressure should be calculated and comment on this plausibility. Another mechanism needs to be suggested by which the water film might be formed.
Concept introduction:
To calculate the pressure exerted on a skate blade below formula is used
Here, P is pressure, W is weight of skater and A is area of blade.
