In a similar way, newly fallen snowflakes are structurally jagged, and so find it easy to interlock. When this stronger force of friction is overcome by a human foot stepping down, there is a sudden episode of slip, resulting in a sharp sound that you hear as the crunching of snow. Older snow has slightly melted, producing a rounded spine structure with a lower coefficient of friction, so slip occurs more readily, and with less noise.A similar effect happens when railway lines are wet. The slip then happens more readily so the engine driver has to reduce his power level to counteract this. The infamous ‘leaves on the line’ excuse really happens. The leaves have to be damp and greasy, of course, and so you get more slip, making it difficult for the train to obtain the traction for going fast.”Reg was quick with his praise. “Thank you, sir, for that clear explanation.

A guy named Russ and his girl Terry had a bunch of people over. Some came as couples and others single like me. Charlotte was there and she was bummed out as this guy Rick was supposed to meet her there but he showed up with someone else. I was talking with this blonde cutie named Donna when Charlotte asked if she could speak to me for a minute. ‘Can you meet me in the garage in a few minutes?’ she asked. I told her I would but I noticed that.
