A museum curator moves artifacts into place on many different display surfaces. Con- sider the following table giving approximate values for coefficients of friction: Materials steel on steel aluminum on steel Ps k 0.74 0.57 0.61 0.47 rubber on dry concrete 1.0 0.8 rubber on wet concrete 0.5 wood on wood 0.2 glass on glass 0.4 waxed wood on wet snow 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 0.4 0.9 0.14 What is Fs,max for moving a 144 kg alu- minum sculpture across a horizontal steel platform? The acceleration of gravity is 9.81 m/s. Answer in units of N. A museum curator moves artifacts into place on many different display surfaces.
