A museum curator moves artifacts into place onmany different display surfaces. Consider the following table giving approximate values for coefficients of friction:
The acceleration of gravity is 9.81 m/s2 . Materials μs μk steel on steel 0.74 0.57 aluminum on steel 0.61 0.47 rubber on dry concrete 1.0 0.8 rubber on wet concrete - 0.5 wood on wood 0.4 0.2 glass on glass 0.9 0.4 waxed wood on wet snow 0.14 0.1 waxed wood on dry snow - 0.04 metal on metal (lubricated) 0.15 0.06 ice on ice 0.1 0.03 Teflon on Teflon 0.04 0.04 synovial joints in humans 0.01 0.003
a) What is Fs,max for moving a 164 kg aluminum sculpture across a horizontal steel platform?
